well, I don't think being on pace for 90 is very sustainable, but who knows.
For what it is worth, one league I am in has a notroiously bad player. So bad its like rolling the dice, because you can't predict how he values players. Sometimes he gets ripped, other times (and I'm serious) he asked for pujols AND a replacement closer for billy wagner, because at the time, pujols was "unproven". He just offered a blow down the doors offer of randa and tony clark for him.
I don't think cordero istradeable though. his era/whip are awsome, he's got good k ratio and his saves will decline, but everyone expects them to as well. ride that train.
