I have 200K Howie Clark in an OL. Real life stats: .302/.362/.396 in 58 PA. For me he's hitting:
.409/.435/.545 in 46 PA
I have 2.5M Shane Spencer in a 90M theme. Real life stats: .373/.411/.910 in 73 PA. For me he's hitting:
.200/.310/.307 in 87 PA
(Spencer had 14 PA where his fatigue was between 92-97%, otherwise he was always at 100%.)
I am left to conclude that Howie Clark may, just possibly, be the better bargain.
Seriously, I've used Spencer about half a dozen times now, and always been disappointed. I know a 73 PA batter will be more of a crapshoot than a full season batter, but has anyone ever had a Spencer season that was worth the salary?
