Beyond the fact that you're not really providing much backup to this claim, you're saying this like it would be a bad thing. If he helps the team make the post-season and go on a good run for the next couple of years, I don't see a problem there. I will gladly take his services.
Furthermore, I don't recall anyone in here planning his whole MLB/minors/whatever future out for him. People wanted to give him a chance and he delivered pretty nicely initially, no one was or is really expected lightning in a bottle.
