From what I've gathered is stuff seems to translate into Ks control into BBs and movement a combo of Avg and Ks.
SPs will get hit but if they can strike out batters they'll get out of jams easier.
MRs need to control and fool hitters and not allow hits to maintain leads I don't need so many Ks.... That said I could be completely wrong... Just a few things I've noticed lol. What do YOU like OM? When you point a finger at someone you have 3 pointing back at you!
