Going to assume it's a 5x5 league. (When I say that, I'm talking about standard categories: AVG R RBI HR SB / ERA WHIP W K SV)
In general you've got a pretty good team. You've got a solid core of hitters. Your 3rd OF spot is bit weak; with Sizemore you really don't know what you're getting there. You've got some dead weight on the bench - a lot of those hitters could live on the FA list easily. I'd exchange them for some high-upside pitching, maybe a closer-in-waiting or two, especially if it's an H2H league.
Example: drop Molina for, shot in the dark, Brandon League. Drop Ryan Ludwick for Madison Bumgarner, Bud Noris... I dunno, I'm trying to guess who'd be available.
