Olerud was a seriously above-average fielder too, if I remember correctly. That's a good one. How about Darren Daulton? 113 OPS+, and three AS appearances to show for it. Darren Daulton made me think of Gregg Jeffries. Unfortunately, after bringing up his BR page it appears he's more qualified for the "Lucky Cards players" thread than the "most underrated". It also makes me think of "You're a 5, Jeffries! A FIVE!" How about Andy Van Slyke?
