Back in 2014, it looked like Johnny Manziel had the world at his feet.
He was one of the most exciting draft prospects of recent years coming out of Texas A&M and was taken as the 22nd overall pick by the Cleveland Browns.
"Johnny Football" was seen as a dual-threat quarterback with the physical ability to run with the ball as well as throw it.
And the buzz around him was well justified after he broke numerous NCAA records while in college - but unfortunately, he never lived up to his reputation in the NFL.
Manziel spent two seasons with the Browns, but after a number of off-field controversies, as well as struggles on it, he was released in 2015.
His career stats currently sit at one rushing and seven passing touchdowns, alongside seven interceptions.
Following his release from the Browns, Manziel was unable to return to football in 2016 due to allegations of assault and drug use off the field.
He was also banned for the first four games of the 2016 season for violating the NFL's substance abuse policy, making it almost impossible for him to sign for any team.
But now, ahead of the 2018 season, the 25-year-old has been pushing for a return to professional football.
He's appeared much more focused on social media, posting videos of himself training with the hashtag "ComebackSZN" that suggests he's ready to return.
In fact, he's gone a step further, posting a number of tweets on Wednesday, saying that he would play the game for free.
In a series of posts, Manziel revealed that he's been reflecting on his past and that the only way to go is up, suggesting he wants to get back to doing what he loves.
Of course, talk is cheap. If he stands any chance of making a return to the NFL, Manziel needs to prove he's moved on from his mistakes.
If he does convince people of that, he'll be one step closer to the league. Everyone is aware of the ability he has, that's undeniable.
But the important question to ask is whether any team is willing to take a chance on a player who's caused so much controversy in the past.
Especially ahead of the draft that takes place in April, where a number of highly rated quarterbacks will be on the board.
But if there is a team willing to take Manziel, and if he has put his past behind him, they could be getting a very strong quarterback to challenge in the NFL next season.
