Troy seems at odds with Dallas a bit because I think the job he'd really like to have is President of the Cowboys, much like John Elway in Denver. He knows it will never happen\
If he has even an ounce of self-awareness, he doesn't want a job like that here because it would heap impossible expectations on him and retroactively ruin his standing with the fanbase.
Troy knows his own history. He was constantly signing off on terrible player acquisitions and draft picks. We spent a 1st rounder on a lumbering blocking TE because Troy had tunnel vision for tight ends. He helped shove Chan Gailey out the door, plunging us into the hell of Dave Campo after Gailey took us to the playoffs every year. After he left, I'm pretty sure he still showed up for events like Chad Hutchinson's workout and gave the thumbs-up.
Troy would be a nightmare as a guy running a team. He has no nose for player personnel. No particular knack for picking good schemes. Heck, he didn't even like the shotgun formations when he was a player, so he was arguably behind the times even when he was playing. He'd be even further behind now.
If Troy went that route, he'd Matt Millen himself. Instead of getting to coast on the reputation for success from his playing days, he'd become synonymous with the stink of failure that he'd earn in his attempt to run a team.
