Jesse Crain is no different from any other scrap heap reliever at this point in the Spring. There are some distant reasons to be interested in him, but his red flags are such that there's likely no performance that can put him on the Opening Day roster. He's around because everyone needs to call up a bunch of relievers during the season so you might as well collect as many interesting ones as you can, and really, with his injury history, his recovery is optimistic and hopeful until there's a setback and he's not anymore.
