NFL players living paycheck to paycheck

Many people think that living life as an NFL player is full of wealth, fame and glamour. But in reality there are plenty of players in the NFL that are living paycheck to paycheck. Roughly 380 of the NFL's 1700 players are living paycheck to paycheck. Before the lockout happened many rookies worried that they weren't going to have enough money to get by. NFL owners are being selfish by taking all the money they get and not paying some players enough money.
