I agree with nothingtoproveco's analysis for the most part. In roto, being non-competitive in a category (in your case, saves) will be the difference between 1st and 2nd. But you have quite a good team. The offense is fantastic for a 12-team league. Pujols, Utley, and Crawford are all 1st round talent, so good job getting them on the same team. You're lucky to have a decent back-up to Utley in Cano, but it does shallow your bench (which could be needed for trades).
Aside from lack of saves, the pitching looks decent. The bloom has gone off of Shields' rose, but I fear it's too late to do anything with him besides drop him or bench him. I think getting a good closer without shaking your team up much is your goal. Maybe a sell high on Escobar. I don't trust Cust or Iwamura to pick up the slack as an everyday player for losing a hitter, but you could investigate the value you'd get for dealing a stud in a multiplayer deal. The team is awfully good as is, so just a little bit more might be all your need.
