Personally, I won't miss Whitner one bit. Has he been playing better as of late? Yes. Is he still just an average NFL safety? At best. He will never live up to a first round pick, even if he was on a great defense.
I also agree that football is won in the trenches. I believe dominant O and D lines win games, period. It helps to be stacked at other positions but these two elements are the most important to fill. And please save the b.s. about how a great quarterback could take any team to the super bowl because that's a joke.
I would love to see us take the best premier D lineman with our first pick and if he isn't there at pick 4-8 which we should have, trade down and load up on D line, LB's, and O line depth. Add in some free agency additions (a stud on D,a huge tight end, a solid RT) and watch out wild card spot next year!
