re: WFFBBDL (critical info in OP this is dynasty baseball)
To be fair, the prospect rules are pretty odd in this league compared to previous leagues I've been in with them, where lowball prospects for next year were more important to the almost here players. People had to either add the prospect, or lose them, as soon as they got called up.
Not saying I agree with PP's proposal, I like sitting on players.
