Why would they pay him 13 mil? Did his contract have a "changed my mind" clause in it?
I don't foresee him starting and I don't foresee him being released (cause then the Vikings could get him.)
Personally, I'd pay him the minimum and make him earn the starting spot- which he very well could do.
of course, I would do that for every NFL, NBA, MLB, NASCAR, etc, etc, etc player. Pay the minimum and have a crap load of performance based bonuses.
