I don't know if he was rushed back. They expected his arm strength to get better more quickly than it has, but I don't think that was an unrealistic expectation. Plus, I don't think there's been any harm done to his shoulder. In retrospect, it would have been better to bring him along more slowly, but it's probably not a big deal. In the end, the timeline probably wouldn't have been that different (although he probably would've performed better with the Cubs, but it's not like they're in the middle of a race right now).
