Look, I know it is a little foolish for the Chiefs to pay him that much, but I will say this, Cassel put up what should have been pro-bowl numbers last year (about 70% completion, almost 4,000 yards, 23 TDs and 13 picks).
I hope Trent has a good season, but I don't think he's going to get 63 million dollars if he, lets say, goes 65% completion, 3500 yards, 24 tds and 18 interceptions...oh, and lets also say, 8-8.
If he hits 70%, 4k and 2.5:1 TD to int ration, maybe.
