Bonds, Grissom, and Alou will be the starting OF's unless the Giants bring in a defensive minded CF.
Bonds and Alou both will get drafted. Grissom is a guy who is always overlooked. I always manage to pick him off the waiver wire, and he always helps my team.
As for the backups, Tucker can play all 3 spots (notice how I didn't say well though
) The 5th OF spot will probably go to CF Jason Ellison. Very strong defensively, and he has some speed. However, not worth owning in fantasy leagues.
