Everyone likes spending in FA or using cap space to gain a little extra value in a trade, but the bonus structure was made clear a long time ago and budgeting is part of the game... as Colby mentions, we've already delayed the draft past the MLB calendar, the 2010 draft should not be on the 2011 books.
Teams that do not have any cap room at all can pick any player outside of the top 64 at no cost - no picks need to be forfeited.
