If he settles at 15-30 runs above average and mainains his current defense, the above chart would show he's fairly easily repalced for considerable savings.
There lies your gamble.... all those LH relievers won't help his cause out in LF though eh?
With the footwork required to play 1st, I really can't see him there.
I can, the guy played it a mess and he's not that bad out there, I'd like to see them try it... I'll liken this Dunn year to Frank Howards's 1963 or 64 and Killebrews 1968 or 65 season. BA variance in power guys games can be ugly.
