I'm not sure I understand what the big deal is here. Who cares? They told the guy they won't franchise him next year after he caved and showed up at camp. I really can't see this setting too much of a "precedent." And, frankly, I don't really think the Patriots care about "precedent." They are going to do what they are going to do in every situation for the best of the team.
The patriots are all about taking the 51 percent play over the 49 percent play. Maybe given the FA market they are not prepared to pay him $9 million anyway. Maybe they decided a happier Asante is worth more than they are giving up. Maybe they are still hopeful of getting a deal done with him next year and see this as free good will.
All in all, it seems like a lot of bellyaching to me. Actually, it sounds like fans with resentment. I'd prefer the Patriots took the emotion out of it, rather than trying to exact a pound of flesh, and made the best judgment for the team.
