The Patriots have been saying good things about Boutte throughout all of this - his professionalism and attitude etc. and using him as an example to other young players.
Todd Downing spoke highly of Boutte’s professionalism on Sunday.

I think it's clear that they weren't going to extend him and given that his YAC was so low (like 1.5 yards on average), I think other WRs likely moved ahead of him and he would be fighting for playing time, even behind Williams (who has an 8 YAC average.)
I think treating players well/fairly when you're potentially going to cut them DOES have a positive impact, but more so with veteran players when you're trying to convince them to sign as opposed to a guy coming off his rookie deal. If they're going to a team that treats them like property with no regard to their future, that IS going to come back to bite you, and we've seen the Pats in this season and other season release guys early so that they have a chance in another team camp.
I think Belichick would often do this and that generated interest among quality depth veterans, who we always need. As a former player, I think Vrabel understands this even better and is inclined to voice this with the front office.
Word gets around the league and having a player voicing that the organization treats players fairly or unfairly can impact future signings.
Worth noting that the Pats sent Boutte to a team where he's less likely to be riding the bench in a contract year - so he's got a HUGE opportunity to play for a decent payday, which he didn't really have here playing behind Brown (and possibly Williams).
That doesn't go unnoticed by the players either.
