12. Geno Smith and IK Enemkpali
You might think a professional athlete might have more to worry about than a measly $600. However, if you’re former New York Jets’ defensive end Enemkpali, then every dime counts when you lend cash to somebody. It’s just as much about the principle as it is about the actual sum of money. Starting quarterback Geno Smith discovered this the hard way.

Smith bailed on Enemkpali’s summer camp after agreeing to attend. The latter had paid for his flight ticket and demanded that Smith pay him back. Then Enemkpali confronted him in the locker room and broke the quarterback’s jaw. Needless to say, this didn’t end well for either man. Ryan Fitzpatrick became the starting quarterback and the Jets released their linebacker.
