went 0-7 in Week 1 Youth Eric Ebron Jersey , the worst start by a group of new head coaches in NFL history. The previous worst was 0-6 in 2001.It took Aaron Rodgers coming back from a knee injury and leading the Packers back from a 20-0 deficit to spoil Matt Nagy's debut for Chicago.Jon Gruden returned to Oakland and his Raiders had a 13-10 halftime lead before the Los Angeles Rams turned it into a rout in the second half.Matt Patricia endured the worst loss of the seven new guys when rookie Sam Darnold and the New York Jets whipped Detroit 48-17. The Lions can only hope Patricia fares better than other members of Bill Belichick's coaching tree did after leaving New England.Arizona's Steve Wilks didn't have a chance against Washington. Andrew Luck's return for the Colts didn't help Frank Reich earn a win against the Bengals.Eli Manning's pick-6 ruined Pat Shurmur's opener with the Giants. Mike Vrabel and the Titans endured long weather delays in a loss at Miami.None of the seven teams play each other this week, so 0-2 is still on the table for all the new coaches.Here's a look inside more numbers going into Week 2:SO MUCH YELLOW: The first weekend saw more penalties (255) and penalty yards (2,254) than any Week 1 since the NFL expanded to 32 teams in 2002. The Falcons led the way with 15 in an 18-12 loss to Philadelphia. The Eagles and three other teams had 11. The Steelers had 12. The Raiders had the most penalty yards with 155.SCORING OUTPUT: The 765 total points were third-most in a Week 1. The Jets and Buccaneers led the way with 48 and the Ravens had 47.TAKE IT TO THE HOUSE: The 12 return touchdowns in Week 1 were the second-most in an opening week since the 1970 merger. There were 13 in 2011. The Jets had two return touchdowns and became the third team to score a touchdown on a pass, rush, interception and punt return in an opener. The Dolphins and Titans had TD returns on kickoffs in the same game, the 10th time that's happened since the merger.DOWN TO THE FINISH: Ten of the 16 games were decided by eight points or fewer and four teams — Cincinnati, Denver, Green Bay and Philadelphia — had comebacks in the fourth quarter.DO IT ALL: Khalil Mack had his second game with a forced fumble, fumble recovery Youth J'Marcus Webb Jersey , pick-6 and sack in his first game for the Bears. He also did it against Carolina in 2016 while with Oakland. Charles Woodson in 2009 was the only other player to do it since sacks became an official stat.SIZING THINGS UP: The Giants, Eagles and 49ers each have 13 players weighing less than 200 pounds. The Steelers have 14 players weighing more than 300 pounds.CRIMSON TIDE TAKEOVER: Alabama led the way among colleges with 44 players on active rosters for Week 1. LSU was second with 40. Florida had 37, Miami and Ohio State each had 36.MISLEADING STAT: Tampa Bay allowed the second-most yards passing (475) but it doesn't mean the Bucs have the second-worst pass defense. The Buccaneers built a 24-point lead over New Orleans and forced Drew Brees to throw nearly every down to try to catch up. Tampa Bay held on for a 48-40 win.THAT'S SO BROWNS: Since the merger, teams that are plus-five in turnover margin are 403-17-3. Doesn't help the Browns, though. They're only 2-2-1 in those instances following a tie against the Steelers.AGE MATTERS: The Raiders have the oldest team in the league with an average age of 27.6 years old. The Browns are the youngest at 25.2.FOREVER YOUNG: Tom Brady became the third player to throw a TD pass in a season-opening game at age 41 or older, joining Pro Football Hall of Famers George Blanda and Warren Moon.THE PERCENTAGES: Since the NFL went to a 16-game schedule in 1978, 52.1 percent of teams that won the season opener went to the playoffs while only 23.9 percent that lost reached the postseason.AP Pro Football Writer Josh Dubow contributed to this report. While the Colts dropped a game against the Jets that they desperately needed to keep their season alive, one area of their offense started show signs of life. In the second half in particular, the Colts were able to get the ball moving on the ground. Their yards per carry average of 5.5 and total yards of 127 both outpaced a Jets backfield that generated 323 yards and 8.5 yards per carry the week before against the Broncos.If the Colts are able to get some consistency on the ground Womens Al Woods Jersey , the offensive struggles could start to disappear. Reich’s scheme requires the threat of the run to keep defenses off balance and open up the play action passing game.What role did Quenton Nelson play in Indy’s running success? Let’s take a look.Nelson (#56) seals Henry Anderson (#96) to the inside and allows a gaping hole to open up for Nyheim Hines (#21). Center Ryan Kelly (#78) pulls to the left and acts as lead blocker. If Mark Glowinski (#64) is able to get a better block at the second level, Hines has another 4-5 yards.Nelson shoves Leonard Williams (#92) out of the hole and sticks with the block as Marlon Mack (#25) runs through the crease he helped create. Williams had no chance on the play. Anthony Castono (#74) and Kelly both won their blocks as well, leaving Mack free for a nice gain. The rest of the defense was cleared out by motion to the right from Zach Pascal (#14) and Eric Ebron (#85).Similar to the previous play, Nelson simply out-muscles Williams one-on-one in the hole and is able to turn him to the outside. This opens up a crease behind him. Kelly’s well-time block at the second level allowed the run to go for extra yards.Again, Nelson is able to win in the hole. This allows Kelly to quickly move to the second level and get a body on a linebacker. Nelson is matched up against nose tackle Steve McClendon (#99) and keeps him from impacting the play. Strangely, Nelson’s legs get caught up in the pile forming behind him and it looks like he is knocked off of his balance after the whistle.Suffice to say, this is something he’ll need to work on. As noted in the comments of our pass blocking breakdown yesterday, these balance issues are an indictment of Nelson’s skill set and indicate that he has been unable to live up to his draft billing.Nelson works with Castonzo to seal Jordan Jenkins (#48) and allow Marlon Mack to run through the A-gap without pressure from his left side. The most impressive blocks on the play were delivered by Kelly and Glowinski who both got a nice push and discarded the initial defender to get to the next level. It is even more encouraging that Mack had the vision and patience to work his way through the traffic for a nice gain.Nelson takes a big blow from Jeremy Attaochu (#55) in an attempted bull rush. Needless to say, the attempt was ineffective. Nelson anchors and his feet never move as he forces Attaochu outside and away from the play. If Kelly and Glowinski were able to get a better block on McClendon and Braden Smith (#72) was able to seal Williams Womens Clayton Geathers Jersey , Mack would have had even more running room.Nelson blocks down on this goal line run and hits Mike Pennel (#98). He was teaming with Kelly at the snap but Kelly lost his footing (cut him, am I right?). Nelson drove Pennel back into the end zone and onto his back as he got caught up in the feet of linebacker Darron Lee (#58) (expect Pennel to get cut this week too).While this run doesn’t go very far, Nelson and Castonzo drive Henry Anderson well out of the play. If Mack hadn’t hesitated and bounced the play to the outside, there was a chance for a few yards right up the middle of the field.Nelson hits Anderson, passing him off to Kelly and gets out to the linebacker, Avery Williamson (#54). All three linemen to the left side of the field get strong seal blocks and open up a massing running lane for Mack behind them. If this is a sign of what to expect from a healthy Castonzo, Nelson and Kelly, the Colts should have some success running the ball moving forward.Again, Nelson gets a monster push on the interior http://www.thecoltsfootballauthentic.com/darius-leonard-jersey-authentic , aided by Castonzo. He releases to the second level gets a final push for Hines on an inside run.ANALYSISNelson had a strong performance blocking for Hines and Mack. He won match ups one-on-one against a variety of different defenders, effectively sealed in the trenches, and helped keep running lanes alive by getting to the second level. The combination of Castonzo, Nelson, and Kelly on the left side looked particularly effective on the ground and could signal more consistent running success moving forward.
