Tony Romo has only been in the broadcast booth for two years, but it's clear if CBS wants to keep him with Jim Nantz, they are going to have to fork over some serious cash. According to Michael McCarthy of Sporting News, Romo is looking for a contract extension that pays him eight figures annually to remain with CBS past 2020.

Romo and Nantz are a great pair in the booth, and he has gotten a lot of attention for his ability to call out plays before they happen. McCarthy speculates that if Romo doesn't get a big contract, he could become a free agent and join another network, or maybe even retire:

But Romo could also play out his rookie TV contract and become a free agent. He could draw suitors ranging from rival TV networks and startup football leagues to tech giants looking to stream games.

There's even a chance the young father and husband could walk away from TV to pursue his growing business interests, sources said. That would disappoint many fans who view Romo as the best thing to happen to sports media in many years. CBS declined to comment.

Romo signed a three-year deal with CBS that pays him $4 million a year. The big question to watch the next few years is how much money is CBS going to be willing to pay Romo. It would seem like the smart move to keep Romo with CBS, but $10 million is a lot of money to commit to a commentator.
