I don't think I would want Griffey on the team. He can't stay healthy and he whines regularly (which I could see the team dealing with if he could stay healthy and put up the numbers). If there was a chance he could stay uninjured for a full season and put up decent numbers, okay, sure, I guess grab the guy.
How would having two big names (Thomas and Griffey) on the team work out in the clubhouse?
