Do we even want Hudson back?
He'll be 33 to start next season. He's tore his UCL twice. He seemed to outperform his FIP this season, and it was the first time in 4 seasons he's posted an ERA under 4. Doesn't seem like a particularly smart buy, especially if his second half/postseason performance drives the price up.
They can non-tender Strickland (and Grace).
I'd like to see Fedde converted to a reliever. He seems to be better as a reliever.
Will Smith and Drew Pomeranz need to be the primary targets in free agency. Will Harris will be a free agent, but he's also 35.
