Cleveland Browns quarterback Johnny Manziel entered rehab last week after a season of well-documented hard partying. “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 off-season was the right time to take this step,” his publicist Denise Michaels said in a statement. Manziel was criticized for being unprepared throughout the season and failed to show up to practice the day before the Browns’ final game of the season. Security was sent to his home, where Manziel was “drunk off his ass,” team sources told ESPN.com. His off-the-field partying included drinking on floating swans and being found with a rolled up bill in a bar bathroom.
