I don't think it's about breaking out, it's just about even putting up an average year at this point for him. He's a career .277 hitter (and that's adjusted by his current .199) so his average SHOULD improve as the season goes on. If the average improves the SB will come. I think last year wasn't really a fluke, just a career year. He should still be a .280, 15 HR, 20 SB guy in an average year. Anyone that over drafted him based on last year's numbers were due to be disappointed.
Edit: Also, his 10% K is the best of his career while his .205 babip his the worst of his career. I don't think he'll suck forever, it's just a matter of if you can afford to let him sit or not.
