Yasiel Puig
Yasiel Puig was in line to be MVP multiple times, but his attitude got in the way. He was such a troublemaker that he gained that reputation, which made it hard for him to find work. He's not with the Browns anymore but has declined multiple contracts for other teams.
Not Enough
He declined all of the contract offers because he thought that they were "too low" when they weren't. This guy needs an attitude check, no one likes a bad vibe!
