I feel this needs to be said. I'm not trying to be a downer on the "optimism", but I think it might need some tempering. Those that point to 2011 and how long it took them to get to .500 in comparison to this year, keep this in mind. When they righted the ship in 2011, they went on an incredible tear over the middle 4 months of the season. I don't think this current roster is capable of that. I think they'll hover around .500 through the end of May, maybe a little over, and it wouldn't surprise me if they were still around that mark by the end of June.
When the OF gets Ellsbury and Crawford back, Bard moves to the BP for his innings limit, Matsuzaka returns, if Melancon figures out how get AL hitters out, and Bailey returns, then I think they could go on a good run. But, right now, I'm not sure the current roster can do what last year's team did during those middle 4 months. Which is fine, just stay within shouting distance over the first 3 months, and finish strong. That should be enough to make the October dance, and they could be quite good by then.
