Ok. Half my offense is on the DL. I dont know what the hell I'm going to do. Huff, Jones, Griffey, and now maybe Derek Lee are all hurt. I'm in second place in a 5x5 roto league that counts R, HR, RBI, SB, and Avg...K,BB,W,SV, and ERA. What do I do? I'm getting beat by a guy who's having a monster week, and I'm having a good week myself. Do I need more pitching depth? Offensive Depth? Or should I wait it out for a bit? I was thinking about offering Cordero or Fuentes for a pitcher, but I don't know what's a fair return. And for my crowded OF position, what should I do? HELP!!!!
