only thing that sucks about having too many categories is then people will manipulate the categories - to take advantage of them...
I can demonstrate if you want but it would take a few minutes.....
basically it's the idea of punting several categories intentionally (predraft) and drafting all players intentionally to work towards winning the reamaining categories.
say for instance
hitters: R 2B 3B HR RBI SB AVG OBA SLUG
pitchers: W L SV HLD CG ERA WHIP Ks BBs
it's fairly easy to imagine tossing some cats in this league:
lets say first of all you said to your self - no speed - all high avg sluggers. that's going to probably win you - 2B HR RBI AVG OBA SLG, that's 6 of 10 bat categories, and you'll be competitive in runs and 3B.
Then with pitching you know right off that CG are rare, so you can see there's really only 6 pitching categories. (assuming you forget about CG) so now focus on who gets good whip, ERA, and low BBs? closers and setup guys. so focus your draft on closers and setup guys.
And what do you know - you could draft based on this strategy - go with all hitters the first 10-12 rounds - and still get some decent closers and lots of good setup men.
now hopefully those guys won't get you many losses - (even crappy closers only get 4-6 losses on the season - as opposed to medium starters who get 8-10)
so toss Ks and Ws, and win saves by getting 4 crappy closers, win holds with your next 4 picks with 4 good setup men, and boom your team is fine - and you don't have to waste any top 10 picks on pitchers. by round ten you'll have awesome power bats and win the league.
so if it were head to head each week you would win
about 6 or more of hitting cats...
2B, HR, RBI, AVG, OBA, SLG, maybe 3B, maybe runs
and you win 5 of the pitching categories...
Sv, hlds, ERA, WHIP nearly guaranteed - with all relievers you got a great corps.
L, BB - you can't get many losses or BBs with no starters and all your guys pitching 1-2 innings
so every week you win a close game like 10-8 or 11-7, but it would happen nearly every week.
It would be impossible for anyone to beat your team.
I played in a league with 13 hitting categories and 12 pitching categories about 2 years ago. I wiped the floor with the competition using similar strategy as outlined above.
that's the disadvantage to playing too many categories - is someone will take advantage of it......
