Williams in hi-cap leagues ($140M, $150M or unlimited)?
It all depends on your team. If you need HRs, do not have a lot of extra money, expect to face some LHs and are playing in a hitters park, then he can be adequate.
In hi-cap leagues most hitters performance is going to be based upon the hitters card, so expect Williams to have sub .200 BA and sub .250 OBP but 50+ HRs and about 20 errors.
Suggest in hi cap leagues you focus on OBP and power. So if you have Aaron, Mays, Hartnett, McCovey type guys, who are awesome players, but have sub standard OBP, Williams is probably not the guy.
Here is Williams on a $140M team. He did what I wanted, hit a lot of HRs and played good defense. But the BA and the OBP was ugly.
http://onlinegames.strat-o-matic.com/team/1391727I saw some numbers from another $140M league where he was about the same, good HR power, good defense but lousy BA and OBP.
Best of luck!
