I have 6 OFs (Bay, Garrett Jones, Ibanez, Lind, Morgan and Rajai Davis). Because I need steals I have to start the last two and have to sit two of the first four. I'm 1st in runs, 2nd in HRs and 3rd in RBIs. Felix would be a nice pitching upgrade.
I think it's fair... Your OF isn't blockbuster, but if you think you're solid in your cats, it's alright. I'd propose Bay for Felix + an upgrade to a bench guy. We're getting to that point when bad teams start shutting down their stars.
