Preparing for our league Zito, eh...
I will try to explain the rules. You have your basic 5x5 12 team roto league.
The points system works like this, for each category you are ranked by how well you compare to everyone else in the category. For example, lets take hrs. If you have 25 hrs and that is the most in your league you would receive 12 points, because there are 11 other teams in your league plus you. If your team only had the 6th most hrs, then you would only get 6 points. Note that the stats are cumulative over the whole season. This scoring is used for every category and the teams are ranked by who has the most points.
Some quick pointers of h2h vs roto
Booting a category in roto is much harder than h2h. You deny yourself of more points in a roto than in a h2h so booting is harder.
Sometimes in h2h i have all my bench players as SP, so that i can get more starts in a week than my opponent, and thus win W's and k's, hopefully. In roto you have 1250 IP maximum over the year, so you can't waste your innings. You can still do some matchup starting, but you want to make sure that your studs always start. This makes ratios more important because your innings are limited and you want to ge the best value possible out of you innings. So closers become more valuable (Gagne's numbers were arguably = or better than Prior's last year in a roto league, although that is an argument for another day). Guys like K-ROd are owned in most leagues because of their excellent ratios. Also, the IP limit prevents picking up SP for their start and dumping them after, because everyone is limited IP (roto excells over h2h here).
Enough advice for you, since you are a potential league mate next year
