The premise of my response is simply that our pass rush has worsened compared to last year (how could it not when you take away KVN?). That was apparent last night. UConn didn't have all day to throw, but the UConn QB wasn't rushed as much until the 2nd half, and even then you've gotta believe that Texas will have better pass protection than UConn.
So, yes, 4 sacks was plenty against UConn, and so was the pass rush. Against the better teams in our schedule, and to say that our pass D will be better than last year, I think that aspect needs to improve.
