I didn't see him say anything about innings. I have long had the belief that something is fundamentally broken with the way they set pitchers up for the majors. Too much failure with too many great prospects to conclude otherwise.
Keegan Akin and Dean Kremer? I'm not sure that anyone important other than the Angeloses were even with the organization when Gausman was coming up, much less The Cavalry. You can't really put the Rick Peterson/Rick Adair disfunction on the current organization.
Even if you want to look at the more recent past, Bundy and Harvey had freak injury problems, and Bundy was still somewhat a success. Gausman wasn't exactly a failure, he probably could have been better, though it took three orgs post-Baltimore to get this kind of success out of him. No other "great prospects" that I'm aware of.
