but his fastball velo is on the downward trend (93.8-->93.2-->92.6 the last three years) as his projective(is that a word???) stats continue to worsen.
He scares me a little too much, so unless the M's training dept (who doesn't instill a ton of confidence in me just yet) sees a clear reason to expect him to regain velocity, I'd have to 'pass' if the other options are on the table.
Still, if you were going simply on past results, he'd stand right up there next to Darvish and Arrieta in terms of overall value created.
