For the second consecutive season, Johnny Manziel may have committed to a major lifestyle change in the offseason.

Last year, that change involved an entrance, this year, it's about an exit.

Johnny Manziel Could Turn Allies Jerry Jones, Stan Kroenke Into Enemies

Manziel has broken up with girlfriend Colleen Crowley, according to Terez Owens.

"Single Johnny Manziel hit up So & So's in Dallas Wednesday, our source tells us Manziel was a bottle poppin' fool," Terez Owens reported. "We received news that Johnny Manziel's EX girlfriend Colleen Crowley has deleted all the pictures she had with Johnny on her Instagram."

Nor does Manziel have anything on his Instagram account in the last year with Crowley.

Incident With Girlfriend Puts Johnny Manziel's Career Back In Jeopardy

The two began dating a couple of months before the 2014 NFL Draft. The hope was that having a girlfriend would settle down the former Heisman Trophy winner.

That did not happen.

Manziel's entire offseason -- before and after the Browns selected him in the first round -- was littered with photos of him partying at various sites on social media.

After a disastrous first season, Manziel entered a rehab facility for a 10-week session for undisclosed reasons. He seemingly had gotten his priorities in order and did not make any offseason news before the 2015 season.

Manziel started as the backup to Josh McCown but was inserted in Week 1 when McCown suffered a concussion. Manziel beat the Titans the following week.

But his off-field problems began to resurface in mid-October when police were called to the scene near his Avon, Ohio, home after reports that he and Crowley were arguing on the side of the road. Crowley accused him of pushing her head against the passenger window and he admitted to drinking.

From there, things deteriorated quickly.

Manziel was reported going on drinking binge during the Browns' bye week. He then missed Cleveland's season finale after being spotted in Las Vegas the day before.

Crowley didn't appear to be part of the solution to Manziel's partying ways, but is a single Johnny Football better for a football career that's already in peril?
