1) There is absolutely no question that Troy Brown would be more valuable to the team than whatever scrub is brought up from the Practice Squad each week.
2) Even if Brown is inactive each week, he is valuable insurance against injuries at WR, PR and at CB. We have often had a veteran or two on the squad for this kind of insurance.
3) Clubhouse presence is not what we players for, although there do need to be team leaders. We have plenty. Players don't need to play additiional years because of a lack of clubhouse leadership.
Unit leadership is another whole issue though. Brady leads the offense and has his hands full without being the lone policeman for the WR unit. We lost a captain in Graham at TE too. K. Brady is a veteran presence, but not a veteran of this system and team. Watson has his hands full worrying about Ben Watson. Thomas is a second year player who saw little game time last season. Bam and Kight are PS'ers. Caldwell and Gaffney are short term signees now fighting for their NFL lives going forward who may be more concerned with their own situation than a units. Stallworth and Washington have yet to show they can lead (or in Kelley's case even play) in the league. Welker seems to have the work ethic and drive to be a leader going forward but as a first year slot WR and PR it would take time for him to build a base from which to lead.
4) Make no mistake, Troy will not play much unless there are multiple injuries. He will be inactive unless he can beat out the STer's for playing time.
And we never have those...
5) Sure, Troy would like to stay in New England. If he truly wants to play yet another year, he needs to assess whether he wants to be play on a team where he would be more of a major contributer.
My gut feel is that it is time for Troy to retire, but that is a decision for him and his family to make. This year the team will not beg him to come back to fill a critical role on the team, as was the case last year.
I would be fine with him playing elsewhere. That is his decision. If he wants to try to catch 30-50 passes for someone this year and help a team to the playoffs, I wish him well. I DO hope the team is in the NFC. He considered NO last year.
