Manziel received a four-game suspension for violating the NFL’s policy on recreational drug and wound up sitting out the entire 2016 season.
Marvez points out that Manziel is currently considered a “Stage Two” offender, which means he would be subject him to random drug testing if signed by an NFL team.
The idea of him volunteering for testing is that Manziel is trying to show NFL teams that he is committed to turning around his life and salvaging what’s left of his football career.
According to Marvez, Manziel is working with quarterback guru George Whitfield Jr. and trying to get back into game shape.
It’s worth mentioning that Manziel could still be subject to discipline under the NFL’s personal conduct policy for a domestic violence charge against his ex-girlfriend, even though he reached a plea agreement back in December.
Manziel, 23, is a former first-round pick of the Browns back in 2014. He was in the second year of his four-year, $8,247,250 rookie contract when the Browns cut him loose at the start of the 2016 league year.
In 2015, Manziel appeared in nine games and thrown for 1,500 yards while completing 57.8 percent of his passes to go along with seven touchdowns and five interceptions. Manziel has also ran for 230 yards. Pro Football Focus has him rated as the No. 31 quarterback out of 36 qualifying players.
