Well, I don't think the Twins are going to win 100 games again... maybe the White Sox will be better, they added stuff.. The Royals don't have enough dudes and I think you're really overestimating how shitty the Tigers can be.
All that said, I don't think the Indians win the division without a lot of things going right (and the Twins having a few things go wrong), but, I don't see a net loss in production personnel wise over last year if they're healthy. I thought Bieber would get figured out last year. Whoops.
There are enough dudes there to win, but I don't know if there's enough dudes there to get deep enough in enough games with so much bullpen uncertainty. And to be honest, lots of teams are wondering the same thing (I'm looking at you defending WS champs), I imagine, and of course you get the games back by exploiting them. Who knows, its gonna get weird but Tito's penchant for throwing the best relievers in the highest leverage situations is going to get more pronounced I think. Overall though, I don't see how this helps KC or Det.
