Casas tore the cartilage in his ribcage. Since cartilage has very little if any blood supply those injuries take forever to heal-if they ever do.

Interesting--very. So two strikes against that injury. The first is that it happened while swinging the bat, which Casas absolutely must continue to do to remain in baseball. The second now is that, not only must the Sox and Casas rely on "natural healing," but it could take forever.

What do you see in the Rays that convinces you they have more talent?

Wander Franco. Oh, wait.

Ligaments and tendons are the same way: they lack a blood supply as well. Thats why the medial ulnar collateral ligament that gets torn in players requires a replacement if its bad enough: it won't heal or at least it won't heal well. Same with the anterior cruciate ligament (ACL) in the knee. I think that Casas' injury might heal over a long period of time with some scar tissue, but he might always feel it tugging as scar tissue is inelastic.
