I liked Moss, was very happy when they acquired him, thrilled with his performance in 2007, pleased with the way he played with Cassell in 2008, and reasonably satisfied last season. I was just "OK" with what I saw from him so far this season. Yes, I hate to see him gone and don't think they are a better team today than they were yesterday.
It did not take me very long, however, to understand why this makes a lot of sense for the Pats, even for this year.
For starters, one thing I definitely did not like about his performance, including in 2007, was how it always seemed to slow down later in the season and in the playoffs. Even in his prime this pattern played out with him every year. Frankly I expected this to be the case this year also, and keeping in mind that someone, or more likelhy a combination of someones, will take his spot, I think it is very questionable to believe that they will be losing significant production.
Second, looking at his overall production for the 4 games he played so far this year, I have to conclude that he is not nearly the player he was even 2 years ago, and that at 33 years of age it is very unrealistic to expect Moss to ever play like that again. He is a diminishing asset, probably diminishing at a faster rate than many of us suspect (since we are looking at his past and not what the coaches see on game tape and every day in camp and practice). Like it or not, all teams make moves like this, trying to maximize the return they get for their assets. It is rather obvious to me that he would be difficult to sign after this year, and thus I think the money is better spent elsewhere, so it is great that they got more value in return for him now than they would have gotten if they held onto him and he walked after the year.
Third, I think there is considerable reason to believe Bruschi and Brown, and others, about the rumors of Moss' discontent. We are all familiar with his history, it is a very long history of this type of thing, and his meltdown after Game 1 validates this rumor significantly in my opinion.
