You know, he may get the knee back to 100% for next year.
But I wouldn't completely count on that, much less that he's going to fix what looks like a miserable plate approach.
IMO, he should be trade bait 1A or 1B (along with either Latos or Leake).
Get some decent prospects for the two. And save the $20+ million or so they'll need for the 42-year-old shell of Joey Votto.
