As a 25+ year professional fantasy baseball player
, I would steer clear of ESPN's leagues.
CBS and yahoo work much better IMHO. ESPN always has some bugs to it. If the stats don't work right from the beginning, the newbies will lose their way and not want to play again. Also, I would strongly suggest you set up rules for trading, or better yet use FAAB$$$ for free agents and play NO TRADES, like the NFBC. Much more enjoyable when you don't have the Moe, larry, and curly trades for A-rod in the first week with newbies that don't know wTF they're doing. it will destroy your league from the get go.
I'd play but I don't really want to beat the stuffing out of you fine fellas here and I don't need the money that bad. FUDD
