Power hitters benefit due to having HR, TB, SLG, and OPS. With power stats being counted that many time I'd consider forgetting about speed completely. You can easily be well above average in HR, RBI, TB, SLG, OPS, OBP and you won't be hurt in AVG, R, and maybe even SB%.
The pitching categories really are a mess. It's a H2H and you have CG, SHO, and NH? 26 pitchers threw more than a single complete game last year. 13 threw a shutout. Those cats are a crapshoot. So I'd pretty much forget about them when figuring out pitcher ranks. That leaves 10 pitching cats. If you load up on good relievers then you'd be well above average in L, SV, HLD, ERA, WHIP, and K/BB. Then if you get lucky you'll come out ahead on CGs and SHOs.
