That's really encouraging. I'd been kinda assuming that he'd need TJ or something major, and would spend all of next season doing rehab kind of like Smiley has this year. The concept that DArvish might be "completely healthy" in spring sounds good.
I wonder if whatever was wrong with him impacted his pitching before he went DL? He didn't seem to have any command of any of his pitches, not even his fastball. I suppose it's hypothetically possible that if his arm wasn't extending correctly, or was hurting and thus causing him to do weird stuff to moderate the discomfort, maybe that might optimistically be remediated next season?
Not likely, I assume he's just wild at this stage of his career. But would be fun if he could throw strikes more consistently....
