Its a good deal for both sides. Longer term contract for Pierce and he ends his career with the C's. The fourth year is an option. With two years still left with Garnett, the C's have a legit chance to win the East again and this deal frees up cap space to sign some new guys. Ray Allen wants to return, but we'll see about that. They need to sign a big man with the Perkins injury and Rasheed gone. Eventually the tank will dry up, but I think the C's with the right move or two to solidify the bench will be a really solid team for another couple seasons.
