yeah, u have a slightly similar team to mine, and have guys i would want. i think u jus need that extra outfielder. winn and nixon arent great. i would probably put bradley in for winn actually. i think another good starter would turn ur staff from good to great. nice pen should get u some saves, and i like harden on the becnh incase he explodes!
i like your team! maybe try and package a few bench players or one of those starters like penny for another good starter (penny is good but you can do better).
