Not really sure that I could justify moving a 1st for him in a straight up deal because I think the Wiz pick will be halfway decent next year. I don't know if you'd be interested in adding to him or if there is another smaller piece on my team that you like?
You know Diaz is a young prospect right? At his age, it'll take him 6 years just to develop. Even then he could be a bust. By the time he's developed, you'll have to give him his 2nd contract and you'll already have 100M invested in him before he barely plays a ML game.
