This is a tough one. I might be in the same position. I have the 5th pick and Bonds and Helton might still be there from what I've heard from the owners ahead of me. A lot of people are down on Bonds because of the reasons mentioned above, but his numbers last year were amazing, especially OBP (.529).
Looking at your categories:
Helton is much younger and the Rockies scored about 100 more runs than San Fran last season.
Both positions are deep, with many good players.
Games played, the last 3 years:
Bonds-153, 143, 130
Helton-159, 156, 160
I'd have to say Helton.
Roger Angell: I was talking with Bob Gibson and I said: 'Are you always this competitive?' He said: 'Oh, I think so. I got a three-year old daughter, and I've played about 500 games of tic-tac-toe with her and she hasn't beat me yet.'
