Yahoo fantasy baseball is really rotisserie lite, compared to the "standard" game, which most of the other sites use.
2 x Util slots? 2 x DL slots? Really? 2 x SP + 2 x RP? As if we can't be trusted to set up our pitching the way we want to?
Old school roto, more or less:
C (1 or 2), 1B, 2B, 3B, SS, CI (corner infield) MI (middle infield) 5 x OF, UTIL.
9 x P
bench and DL varies.
It really does change the way you play when you draft those 4 extra hitters. Getting value in your 4th or 5th OF, CI or MI slot (not to mention those 2 extra pitching slots) could win or lose your league. And if you want a real challenge try 12 team NL only or AL only using that configuration.
I assume this is Yahoo? Well, this is Yahoo, you can do pretty much what you like, and if you're in a private league the commish can do whatever he likes. I once had a commish who locked out the top 7 managers (16 team league) with a month to go, so he could win the league.
Just keep dropping until the roster tool doesn't let you drop any more.
