My feeling is that Asante's recent "nice guy" posturing is designed to forge an agreement with the organization not to franchise him next year in return for his showing up in camp.
I think he came to the realization that with $8 million this year and a $15-$20 million signing bonus next year is a better two year payout than he could get if he signs a long term contract this season.
Is it taking a risk - yes, due to injury, but being the premier CB on a team that looks like a good bet to win the SB will increase his value next year as well.
How long Asante has been playing this scheme out I don't know but I feel in my gut that he's played it exactly the way he intended to AVOID getting a long term contract this season, but has postured well enough to work an agreement to avoid being franchised next season.
If it plays out the way he intends he'll have boosted his 2 year payout by about $10 million in guaranteed bonus money by taking the franchise pay this year and a big signing bonus next year.
