I'm ok with Reich allowing Big Q to have some fun.
I don't know who to blame between A.C. and Joe Haeg though. There was one DT in front of them. Haeg went straight forward while A.C. went towards Center, effectively blowing Haeg off his feet and filling the hole that Big Q was gonna run thru.
I wonder if Haeg was supposed chip the DT and then get to the LB thus allowing A.C. to push the DT towards Center, but when Haeg didn't go to the second level A.C. just pushed everyone in front of him.
