Former Dallas Cowboys quarterback Tony Romo had his debut practice with the Dallas Mavericks this morning, including being part of the team photo prior to the walkthrough, all in his usual white and blue.

The 6-foot-4 Romo wasn't shy about taking a few shots during practice, popping right behind the screen for a wing jumper.

Swish!

Here's Romo also practicing throwing up alley-oop passes to Cowboys teammate Rico Gathers in a pick-up game.

Many say the soon-to-be 37-year-old's distance in his jumper is considerably farther than his passing distance at his age.

Apparently now since his retirement from the NFL, a Mav for a day keeps the doctor away, or so they say.
