I mean, why not, there are so many bad commentators out there it would at least be worth a shot.
Commentators are usually hired because of their voice, ability to think on their feet, initiate and keep conversations going. Analysts are the experts, the ex-athletes or coaches, a good voice is preferable, the rest of their job is taught to them and practiced. In terms of the quality of golf commentators, I doubt it's a field that attracts the best as there is likely more money and opportunity in other sports given the number of games and teams.
Romo could be a 3rd guy, he's not a commentator and his analyst skills are best suited for football, though he might be a suitable analyst for an amateur tournament or web.com
