I agree, I'd like Paul on the team, but I don't see him starting many games in the OF. I didn't think his defense was too good, just based on my own observation.
Heisey will get the most starts of the bench outfielders. I think he'll back up all three positions, and play late inning CF defense.
But that doesn't diminish Paul's role. I see him as providing the LH hitting depth the team has needed for years. He'll pinch hit, come in on double switches sometimes, and start here and there.
