Honestly, I believe Warners problem was that he adjusted to the NFL. When he was fresh out of the AFL, he released the ball alot quicker and man it was hard to sack that guy. As his NFL career went on he began to change his mind on alot of decisions thus giving him more interceptions and more sacks. Then again when you're running game isn't working like it once did that can lead to alot of that stuff too.
As for the Wrangler's, I think they started out good but the season just took its toll on an expansion team. They will be good next year.
