I really like the original post. Cash definitely has more room for maneuvering. More of an art, for sure. But some artists aren't as good at math, which is were tournament players can excel.
In general, I think the OP is correct, but...
Gus Hansen might throw a wrench in that. His tournament play doesn't strike me as hard core math based. On the other hand, he lost something like $5M in cash...but I think some of that may not have been NL Holdem but rather Omaha variants where he wasn't as comfortable (not sure about that last part, but I do know he lost millions in cash.)
