For me, I have to say the biggest disappointment was the OL. I thought they should've dominated the smaller SJS DL. I expected huge running lanes and time for the QB. The 2nd part of that happened for the most part, but they sucked in the running game.
As of right now, this is not a championship team. Can they get there? I don't know. The talent suggests they can, but the sample size so far has not been impressive. Defense has been really, really good at times, but San Jose exposed some areas that more talented teams can exploit if not corrected now. Texas should dominate UTEP all day long, key word is should.
There are two other players (Manning is a given) that really need to elevate their level of play and that is Wingo and Simmons. Both of them have been really subpar to start the year. I would say Simmons has just as many negative plays (penalties) as he does good plays. Wingo has to help Manning out. Sure Manning should put the ball on the numbers, but Wingo needs to make the tough, inaccurate catches as well. That is what makes a receiver great.
