Johnny Manziel entered treatment on Wednesday, adviser Brad Beckworth told ESPN.com on Monday through a spokesman for the Browns quarterback.
"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," Beckworth said.
The quarterback is expected to be in rehab at least a few weeks, but the amount of time depends largely on what doctors recommend, according to a source close to Manziel.
The quarterback is voluntarily entering treatment as a direct result of his lifestyle away from the field, and he informed people in his circle last week that he wants to "figure out his value system," a source said.
This is a mature move by the normally immature Manziel. It's a good sign for his future that he's taking a look at his life and trying to "figure out his value system." To make it in the NFL, he's going to need to act like a professional, and this is a good first step.
