Roy is a great pitcher, knows the game, studies his hitters like the best. He wants out of Houston so bad. Once he gives up a couple runs, he has been taking a step back. He knows that this team won't fight back from down 2-0, or 3-0. Why risk hurting himself and laying it all out when the rest of the team is not giving 100% ever, more like 50%.
He would look great with Boston, NYY, and even Texas Rangers.
