Tyson Fury’s Revival
Fury stunned the world when he dissected Wladimir Klitschko in 2015. However, the heavyweight champion immediately fell into a downward spiral. First, he failed a drug test and the boxing commissions stripped his titles. His downward spiral saw him balloon up to over 300 pounds and he contemplated suicide (via Bleacher Report).

Then he made an inspiring return as he shed the weight and dealt with his substance abuse problems. He reclaimed the heavyweight crown after an exciting series against Deontay Wilder. But Fury proved that it was too good to be true. He befriended the gangster Daniel Kinahan and ducked fights, tarnishing his image and making himself a polarizing figure in the world of boxing.
