It's hard not to admire someone who is so dedicated to his craft. Let's face it, despite the raw talent he did flounder for a few years and he took the responsibility for his own career. The success he has had working with Rapsodo and high speed video has caused all of MLB to take notice and most teams now utilize that technology.
How many times have we seen young pitchers with "good stuff" not be able to harness that and have a successful career? Bauer's use of technology and his public documentation of his progress have been a definite factor in accelerating its usage throughout Major League baseball.
That being said, with everything I have read about him he's an abrasive personality. While some people admire his IDGAF attitude I think that ultimately it hurts him both personally and professionally. He probably wouldn't be the type of guy I would hang around with. But it's his life and he's free to choose to live it as he sees fit.
