I guess if I was a GM I wouldn't really care if a player was close to MLB. A guy like Houser is close to MLB but out of options, so really how much value does he have to a team? If he's bad, it's not like they can just send him down to the minors without the risk of losing him and all of those guys do have a ton of holes. Ray has major strikeout problems, Dubon takes a walk once every decade, Nottingham might not be able to stick at catcher, Gatewood has a career OBP under .300. Diplan should give some of his walks to Dubon. Teams have guys like that scattered all over their system and these guys aren't going to get you much unless they're traded for a flawed MLB player or used as some secondary piece in a package that includes Hiura and/or Burnes/Woodruff/Peralta or something like that.
