David Cobb already has played in four pro leagues. Soon, he might be going for No. 5.

The former University of Minnesota star running back has played in the NFL, CFL, AAF and the Spring League. Now, he’s thinking about the XFL, which begins play next spring.

“I’m definitely very interested in that,” the free agent said by phone from his home in Austin, Texas. “If I don’t get into (an NFL) training camp, I just have to be prepared to take on the next thing.”

After rushing for a school-record 1,626 yards as a senior in 2014, Cobb was taken in the fifth round of the 2015 NFL draft by Tennessee. He rushed for 146 yards as a Titans rookie but was cut before the start of the 2016 season.

That began an odyssey that has included NFL practice squads (Pittsburgh, Chicago), the Spring League, a stint with the CFL’s Saskatchewan Roughriders in 2018 and a spot with the San Antonio Commanders of the AAF before it folded last April.

“I’m not old, but I’m old for a running back,” said Cobb, 26. “But I’m still trying to play as long as I can. Maybe an injury pops up here or there (with an NFL team). If not, wait for your next opportunity.

“There’s a lot of things I want to do outside of football, but I want to play football for as long as I can.”

Cobb hasn’t been on an NFL roster since the Bears released him in May 2017. He had a tryout with the Vikings in August 2017 but wasn’t signed.
