I've never really played fantasy baseball before and I'm sure I didnt draft the best team I could have. I'm in a 10 team head to head league with these stat categories: R, H, HR, RBI, SB, AVG, OBP, SLG, W, L, SV, K, HLD, ERA, WHIP. If anyone has any advice on ways I can adjust my roster makeup or unknown players that may be better then some of the players I have, then that would be great. I appreciate the help in advance.
