Why do you think Seymour wants or needs your or my sympathy, or even Belichick's? Belichick called him and tersely told him his rights were traded. From that moment onward, Seymour was focused on relocating his family and on his role with his new team (and in granting a couple of interviews to personal friends). He has had regular calls with his new team, and reported within a week, apparently ready to play. Also, Seymour and the NFLPA chose to clarify the rules on the 5-day letter.
Personally, I have no problem at all with any of Seymour's actions or comments that have been made public. If there is underlying dirt and unacceptable animosity or issues between Seymour and Belichick, I don't think that we will ever really know the details.
I also don't question Belichick any longer on this deal. If he thinks that the best way to win in 2009 is to dump Seymour, then it is what is, and I can live with it. It is time to move on.
As I indicated in the Week 1 thread, if we don't win this year, it is not likely to be because of deficiencies in the performance of the defensive line.
