No, I realize that you don't have the resources to make the actual hire yourself. I'm just curious who (if anyone) Portland could have hired that you would have been at least cautiously optimistic about. Perhaps no one, since you've lost faith in the people making the hire?
I think what people are mostly saying is that, in the absence of actually being able to do the due diligence themselves, his background in a couple of the aspects related to being a GM (statistical analysis and cap management) and his status within the game as a well-regarded assistant and supposedly hot GM prospect is exciting. None of us are able to make concrete points about why he'll succeed since none of us know him or have talked to him.
My own interest in Cho comes from my admitted bias in favour of sophisticated statistical analysis. I think scouting is absolutely necessary, but I think statistical analysis is integral to measuring player ability in ways that the human mind is unable to do so just from direct observation. The human mind has strengths that computers and math can't duplicate, which is why I say scouting is also essential. I think Portland already has high level scouting minds in Born and Buchanan, so I like the idea of hiring a guy who's considered strong on the statistical side of things. I realize that for people who are dubious of statistical analysis of athletes, that won't be compelling. It's simply why I like the hire, not necessarily why anyone else should.
