I hear ya Kane3387, and my expectations are set to "low" until I see something on the field to warrant otherwise. With that said, my hope is that he's got something to motivate him once again.
In essence, every year is going to be a contract year now because he knows the Pats won't screw around - they'll cut him if they think that he's not a good value anymore.
That isn't to say that he'll be able to get back to pro-bowl stature again, but even if you account for him being a despicable person, he's still going to be greedy enough to want to earn more money.
So we've got that going for us at least 
Hi Jeff,
I think it's a low risk high reward move for the Patriots. You're wise to temper your expectations on this guy. The Patriots are the best organization in Sports imo. They have the best coach possibly ever in any sport in the last 80 years. Bellicheck is an Alien lol. That man is incredible. So I think he has the best chance to get a guy motivated from a coaching standpoint. Tom Brady won't hurt either.
Still I think it comes down to Love though. You have to love football to want to play it more then any other sport because of the beating your body goes through. You have to love football to put in the work to take care of your body as you get older. Look at TO. He loves the game and cares about his place in it. The difference between a guy like TO and Fat Al. TO cares about his place in history. For him it isn't about the money as much as it is getting a SuperBowl and maybe more importantly padding his stats as much as he can so he doesn't get jobbed out of the HOF. He will get there but I don't think he wants to be like Art Monk and wait almost 20 years.
Fat Al is about the money and if he gets the chance to play for essentially one year contracts then depending on how much money those deals are worth, it might bot be worth it to him. It will only get harder for him to take care of his body as he gets older, and if he is as big as they say he is now... Well let's say he is not off to a good start in what is potentially a make or break year. I do think he will be ready to Kick our butts if he is active late in the year.
I don't think it matters though. You guys picked up Stroud, Ellis, and added Andre Carter (who I like) and added them to Wilfork and others. You guys are deep at D-Line and should create pressure and stop the run. I would like to see you guys play more 4-3 actually with two DTs. I think you will too. I like this Patriot's team a lot on paper, but it's all about January for them.
