Has nothing to do with disrespect.. He just isn't the same player, and he should be moved while he still has value. For him and this team. Possibly he could get on a team with a shot at winning a Super Bowl. That would be awesome and something he deserves. He isn't getting that in Dallas.
Stop Jerry Jones thinking here. THIS thinking is exactly what gets this team in trouble year after year. Every football team loses good players and has young players step up..
About time Dallas takes that step. Get younger and start building a new core.
