Henry is right. According to the local beat writers, the main stickler issue is he (his agent) wants to be able to double-dip if cut before the rookie contract expires. I'm not sure if other teams allow that in their rookie contracts or not. The payment of the signing bonus is not as big of deal and front what I've heard can easily be worked out.
Either way, it does look bad for the Chargers front office (again!)....especially now that his mommy is tweeting stuff.
