An alternative solution that might meet everybody's needs is to wait to run the park effects until after the 27 man cutdown. Go ahead and use Ken's figures (109 in a 20 team league) as the CAP where you must be after the 27 man cutdown. As he points out, if park effects increases PB value of certain players, it is likely the cap will also increase.

That way we aren't dependent on the park effects and their subsequent effect on PB values taking place soon enough to allow a fair draft.

Thoughts?
