Dave B - normally I would hesitate to promote a player so quickly, but Bill has taken so well to new environments and does not seem detered no matter where he is, nor the level of competition (so far). Due to our teams circumstances, I would move Big Bill to the 40 Man Roster around mid-August, place Young on the 15 day DL (name your injury) and give Bill a taste of the majors for a two week period - maybe longer depending on his performace. Start him at 1st, and see what kind of damage he can do. Then in '09, place Bill on the 40 Man and start him in Columbus and dump/reassign Larry Broadway (BTW - what IS this guy still doing here? Keeping 1B warm?).
I don't see much detering Bill and firmly believe he will be playing in D.C, if not this year, certainly next year. If he continues his offensive trends, he will be starting in 2010.
