amazinz really covered it well, so ill just add/reinforce what he said
you cant punt any categories in roto since it can kill your entire team if you do...balance is definitely the key in roto
speed is something you need to look at a little more heavily, but i wouldnt over-value it too much
as far as pitching goes, W's are fickle, so just look for good pitchers as you normally would
RP are pretty much what they are, need to get saves, but you can get set-up guys to help with ratios, Ks and vulture a few wins
