I just read John Clayton's article on espn about players likely to be cut due to their team's cap situation. The name that jumped out to me was GB MLB Nick Barnett. If he is released he would at best be an upgrade over Belcher and a run stuffer, at worst he would be good training camp competition.
I haven't heard anyone mention Barnett, probably because he is not a FA this year. I would be just as excited about adding him as I would any of the RT or WR names I have been reading about on AP.
