Last week, a video of San Antonio Spurs great Tim Duncan surfaced wherein the five-time NBA champion was showing off some mad skills during his mixed martial arts training session.

That clip was courtesy of Jason Echols, who's a renowned kickboxing trainer for other athletes and celebrities. Echols recently sat down with Bleacher Report's Joon Lee as the two talked about Duncan's foray into MMA and how he'd fare against the sport's real bruisers:

“[Duncan] would be a legit competitor. For sure. He has a desire to learn and compete. He has the heart for it. He most definitely would be a competitor.”

What made Duncan such a decorated NBA player was his will to succeed. His hard work and dedication paid off indeed as evidenced by his two MVP awards and 15 All-Star appearances. Given the glowing praise that he's gotten from his sparring partner, it's obvious that the future Hall of Famer could be as intimidating in the octagon as he was on the hardwood courts, especially with his significant size advantage.

However, Echols was also quick to advise Tim Duncan to stay away from seriously considering going up against the fighting world's finest:

“I would highly encourage him not to. Being a retired Spurs player, I wouldn't want him going out there and getting punched and kicked by some of those guys, but Tim would be a competitor.”

That being said, it looks like Timmy D's about to take his aggression out on Jason instead with more vicious side kicks during their next sparring session.
