From the games I watched last year so-so, but part of that was scheme as it looked like his responsibility was pass rush, outside contain, run defense over the tackle/te in that order (trying to utilize his pass rushing skills against the play action I guess) even on non obvious passing situations. We can trust Rivera to get whatever is left in Allens tank out as he understands how to keep the dline fresh.
Take julio out and they are a very average team at best. No easy feat as he has proven he can abuse even good, around top ten, corners. But Norman proved twice last year the elite once can do it. So the question is more are they playing any elite corners.
Take away the sideline throw at the end of the half he missed every throw over 15 yards in the air by a mile. So I guess one could say they beat themselves as they would be in it if all those was completed. Or in other words "we lost because i am not good enough" as nothing indicated he will be an accurate deap thrower anytime soon/ever.
