Baseball teams that lose 100 or more games usually want to turn over the roster. The Houston Astros have already done that. Since last July, they have dealt four of their regulars and their best starting pitcher. Rumors have them dealing more veterans this winter. Additionally, sometimes the rookies you bring up work out and sometimes they don't. Astros fans remember Jeff Bagwell, Craig Biggio, Ken Camniti, and Steve Finley.
Fans don't remember Chuck Jackson, Ty Gainey, Cameron Drew, or Eric Yelding. There are just as many young players that flop as those that succeed. It will be interesting moving forward to see which ones make it and which ones don't. Since the Astros will be a team of young players, I'm going to sift through the long list of hopefuls for you.
