What is you're # 1 concern heading into this season?

I been following this board and any update I can on practice and scrimmages. From what I have gathered, our offense will be very good. We get Hill back, we have a young but experienced offensive line with some great new talent emerging in Pocic and Hawkins, Our receivers are now veterans and with Dural back from injury, we now have a legit deep threat receiver to go along with our 5 star receivers back at their natural positions, We have a new tight end that can catch the ball and will be utilized in Cameron's new offense for a much needed change, and We have a senior QB with a year under his belt and two very capable backups behind him which includes what some to beleive a future Heisman Canidate in Jennings. On the defensive line we will feild what I think will be an even better unit than last years. Anthony Johnson, Ego Ferguson, Rasco, and Hunter are all studs and I have a feeling they will be special. Our linebackers in my opinion will be fun to watch this year. We have an embarrassment of depth here and they are all fricking really good! We return Craig Loston whom I beleive is the best player we have on defense and his leadership will show at the safety position. I think my #1 concern is the other safety spot and our corners to be honest. Our corners will have a year under their belts though so it can only be improved from last year and they didn't do that bad for being so young. I think this team will be better than expected.
