Here are the facts folks...Portis had 4 runs of more than 10 yards in the game and all of them were in the 2nd half. These 4 runs combined for 68 of Portis' 121 on the day. Contain those 4 runs for say 20 yards and Portis winds up with around 75 yards total.
So, what happened on those 4 runs?
The first run was a 31 yarder in the 3rd quarter to the left, when Watkins was not even on the field. Brown was actually in the box on that play and got shoved out of the way by Samuels, while Cooley pushed Ware out to make a lane for Portis. Burnett, who was trying to blitz the gap on the right side of the center, ended up getting pancaked by Rabach. Portis was then tripped up by Hamlin coming across the field.
The 2nd run was a 13 yarder in the 3rd quarter to the left, where the entire d-line lost containment and got stretched on a sweep play. Portis easily found a hole behind Kendall and Samuels, who blocked James at the second level to extend the run. Ellis missed with arm tackle falling to the ground, while Canty almost got pushed off his feet in pursuit. Thomas got run over while off balance, while Hamlin and James caught up to Portis and wrapped him up. The Skins had 3 receivers on this play with Jones, Henry and Newman covering and Hamlin the lone safety....no SS (Watkins) to help on this running play.
The third run was an 11 yarder in the 4th quarter straight up the middle, where Johnson was double teamed on the left side. Rabach came off the double team to block James at the second level, who clearly had the angle on Portis coming through the middle. Hamlin was then left exposed and missed the tackle, using just his right shoulder and not wrapping up. However, this hit made Portis lose his balance enough, to fall down and have Watkins clean up with his legs.
The 4th run was a 13 yarder on the very next play to the right side, where Spears got pushed out, James missed with an arm tackle and then, Thomas eventually bringing Portis down with an assist by Watkins.
Personally, I don't see how you can blame Watkins for the poor run defense the Cowboys displayed Sunday. Especially on those long runs, where he was either on the sideline or making the tackle himself. Here are the running plays by Portis and Betts and the totals per quarter....
