Cleveland Browns quarterback Johnny Manziel voluntarily entered a rehabilitation facility on Wednesday to "become a better person," according to reports.

Manziel's adviser, Brad Beckworth, told ESPN that the NFL star realized that he needed to improve on various aspects of his life.

"Johnny knows there are areas in which he needs to improve in order to be a better family member, friend and teammate, and he thought the offseason was the right time to take this step. On behalf of Johnny and his family, we're asking for privacy until he rejoins the team in Cleveland," Beckworth was quoted by ESPN as saying.

Manziel is expected to be inside the rehab facility for a few weeks and the length of his stay will still depend upon the recommendation of his doctors, ESPN's source claimed.

The anonymous source added that Manziel's submission to the treatment facility, is his way to "figure out his value system."

A similar AP report published on Yahoo Sports, quoted Browns general manager Ray Farmer, who said that the team supports Manziel's decision.

''Our players' health and well-being will always be of the utmost importance to the Cleveland Browns. We continually strive to create a supportive environment and provide the appropriate resources, with our foremost focus being on the individual and not just the football player,'' Farmer said in a statement.

ESPN interviewed a few more sources who claimed that Manziel "showed lack of commitment" and preparation for the games which greatly affected his contribution to the teams since he joined the league. He initially promised to be "the guy" for Cleveland, as ESPN put it, and that he would be more serious with his performance in the games to contribute to the success of his team. His actions, however, did not seem to match with his pronouncements as he recently was absent in a walk-through of the Browns after he reportedly partied the night before.

Manziel's time in rehab is expected to bring positive results to the player but Cleveland.com said that "it might not stick" if he is not willing to undergo necessary treatment.

Quarterback guru George Whitfield, who is also Manziel's close friend, said that the NFL player's decision was "the right move" as he said that it is Manziel who knows his situation best.

"Best possible thing for Johnny Manziel. Take your time ... Praying for you, cousin,'' Whitfield was quoted by Cleveland.com as saying.

The entire NFL industry will be waiting for the results on Manziel's submission to rehab and what it will do to his performance and attitude to the sport next season.
