Dude Jeff George was known to have a shytty attitude with coaches and still got multiple chances. Plus he was did not have the playoff success of McNair and wasn't overall considered as good as a QB as McNair. George was considered a pure potential type of dude. It was always if he only did this fight or if he only committed himself. Folks were in love with dudes arm and throwing motion.
Steve McNair was arguably a border line HOF who carried that team for years. He also took that team to the Superbowl and two AFC championship games. There was no reason to lock him out of the work out facility.
The titans literally chained up the door of the workout facility to not let him in. Then they told him to go home and not come back. Only to trade him before the sseason started.
McNair should be an HOFer but will never make it in posthumously now....media would eat that story alive.
