Maybe Johnny Manziel doesn't want to play football anymore.

The Browns quarterback -- for now -- has gone into seclusion since a disastrous end to his 2015 season that had nothing to do with football.

Johnny Manziel May Be In Hiding After Turbulent Season

Former Browns standout quarterback Bernie Kosar said he's tried reaching the embattled Manziel 18 times to offer the second-year player his support and mentorship, only to be completely ignored, according to USA Today Sports.

"If he chooses not to talk to me, that's his choice," Kosar said, according to the report.

"I'm not mad at him. But there's a point where there's an element of respect that's involved."

Kosar is the second former athlete to try to reach out to Manziel. Former NBA player and coach John Lucas also offered his help to Manziel, according to Larry Brown Sports.

The 52-year-old Kosar added the he believes Manziel's partying lifestyle could usher him out of the league at age 23.

"That's definitely a possibility,'' Kosar said. "I'm not saying he doesn't have a chance to change, but that's a possibility."

Public support is dwindling for Manziel. Nike may drop Manziel as a client, according to TMZ Sports.

And yet, Manziel has given no indication that he wants to redeem himself, re-enter rehab -- he spent 10 weeks at a treatment facility last offseason -- or even solicit anyone's help.

Manziel is one of the most scrutinized players in the league, especially in social media circles -- thanks to countless posts of his lifestyle online. Staying out of the spotlight figures to be an appealing option for the former Heisman Trophy winner, if for no other reason than his public exploits are generally construed as negative.

Manziel may not believe that he has a drinking problem. He may simply believe that being in the NFL does not allow him to do what he wants to do without tremendous criticism and is growing tired of being a public figure.

The quarterback still has a few weeks to decide what he wants as the playoffs take center stage, but the longer he waits to plot his 2016 course, the more explaining he'll have to do to any prospective NFL employers.
