The hugest question is just how many errors will Barry Bonds commit in the infield. It better be tons, or thane will just clean up. It will also help that he picks late in the second round, so his pitcher may let more folks get on base than most.
I would have picked Biggio over Rose. At catcher, second and CF, as well as other OF positions, Biggio will provide good defense at key positions. His drop off at SS may not be as steep as Rose's.
