Odom also strikes me as a more old-school guy, so maybe there's nothing he wanted to do, either. Very possible that Sluka tried to play hardball with Odom—mid-season, by the way—and he said something like "Not only no, but heck no"... Agents and contract disputes and players making "business decisions" mid-season are a cancer.
Also, when I look as Sluka's stat line (and consider that the hardest games are behind UNLV) it's very possible that Odom decided he'd rather go with an almost-as-good QB that they can develop and use next year, instead of a problem-child QB that is gone after this season.
