As far as I can tell from this and ESPN's coverage, the total moneys the same as that Rivers rejected earlier but the structuring of incentives is different. I'm guessing someone decided the 4 rings/4 MVP's bonus was just a waste of good ink.
So I guess Chargers fans can be happy. Or at least marginally less suicidal.
The media pounced all over the original contract's incentives...but is such a thing unusual for football? I know in baseball, incentives are common. Players' contracts routinely have bonuses for being selected to the All-Star team, winning or finishing top 10 in MVP/Cy Young, MVP of a playoff series (with escalating bonuses for each round) and in some cases leading the league in certain categories. I remember Bill Swift's Rockies' contract from 1995 had incentives for leading in K's, wins, and....ERA. Winning four Super bowls and MVP's with the Chargers is about as outlandish as leading the NL in ERA while playing in Coors Field.
First off, the play looked (at least to me) like a half-broken play; it might have originally intended to be a run. If that was the case, then he knew Strahan was probably going to get to him anyway; why risk injury?
