I think what he meant is it wasn't enough to uproot his family and play for the Nationals. He would like someone on the Yankees to get hurt so he can gravy train his way to another world series.
I think it is a losers mentality to want to play for a winner instead of opting to play for a currently bad team and help turn them into a winner. Felipe Lopez played poorly while he was in Washington and as soon as he left he claimed how happy he was and that he would be able to play hard again being with a winner. Maybe if he played hard here he could have helped the team win. Dye just sounds like a guy that would be an attitude problem since he wants to gravy train and it would take a miracle for this team to win.
Except that Dye's in the twilight of his career. He's got this year and maybe next year and that's about it. If I'm in that situation, I'm not going to the team that's lost 100 years in back to back years. I'm gonna try and get to a place where I can have a chance at a championship. Why go to a team that's gonna have little reward and just collect a pay check if it's your last go around. Lopez's situation is different, he's smack dab in the middle of his career or at the time, arguably at the beginning of it. He's not in a position to be big timing any organization, if he were looking for a 5 year deal, it might be a bit different.
Dye's in a situation where he can either stay at home and be with his family, spend time with his kids or go play for a team that's gonna likely lose more than they win, especially when he's been on teams that have won. I don't think it's selfish or a losers way of thinking. He's in position to be a little choosy, more power to him. He's essentially this years Pedro for a position player.
