This is obviously true. We all saw the signs of this. Yet despite all of that, it amazes me how competitive we actually were. Most teams, with that kind of mental/physical makeup, are going 3-8 and getting blown out in most of those 8 losses. But, even in that 4-9 season Shula's first year, we were competitive in most all the games. Georgia and Ole Miss beat us down pretty badly but the final scores weren't terrible.Purely anecdotal, but I was in court years ago and one of the witnesses in a battery case was a starting DB for Arkansas back when Brodie played.
I recognized who he was and while we were waiting for the bailiff to open the courtroom, we talked about football, the SEC, etc. I asked him about playing Bama back then and specifically what he (and his teammates) thought of Brodie and his response was "meh, nothing special."
He also said that compared to many SEC teams he played that Bama was mentally and physically weak.
I guess you credit that to a core group of guys that included the likes of DeMeco Ryans. And to some extent, the pure talent of guys like Croyle. As to the original question, I echo others who say Croyle had the physical gifts but without the drive, he would have gone nowhere fast under CNS.
