If he had been arrested on drugs, weapons, or DUI charges or some type of violent crime then he wouldn't be getting any benefit of the doubt, at least not from me. That stems from the fact he was arrested for reckless driving and (non-physically) resisting arrest. Even if he is completely 100% guilty of these charges, it's not a big deal. The only true negative is his resistance, but we don't know why he was resisting. If you go by the statement he is quoted as saying, it could just as easily be an overzealous cop as it is to be a spoiled NFL millionaire.
I just don't see what the uproar is. He didn't commit any of the big no-no's (drugs, weapons, alcohol, violence). Hell, look at his bail. $6500. From what I've read, normally when pro athletes are arrested their bail is 5 or more figures. That should clue us in to how big a deal this is. If he wasn't an NFL player, this wouldn't even warrant 2 lines in the local paper.
