To be fair, he was probably beaten down and broken by '99 - like the majority of the WCW roster at the time. Plus, his name was General Hugh G. Rection - what's the fucking point of putting in any effort when your career and push are DOA anyway with a name like that?
Not that I'm the Bill DeMott defense force - far from it. His training methods were exposed as nothing short of awful. Even on worked/kayfabed shows like Tough Enough, he came across pretty poorly.
Part of is "this is how rasslin' used to be" *spits tobacco* and he didn't/couldn't change with the times, wasn't able to realize that the paradigm had shifted, and was ultimately used as a scapegoat by a front office that willingly encouraged his behavior or at least willfully looked the other way for many years. Not that I'm absolving him of his sins - he was a pretty shitty trainer and person by all accounts, and who knows how many future main eventers he drove away with his bullshit. (Kenny Omega?)
