However, as the #3 overall pick in the 2012 NFL draft, Trent Richardson signed a rookie contract for over $20 million guaranteed, plus a $13.3 million signing bonus. So the lost $1.6 million shouldn't destroy his finances, as long as he didn't blow through the other $13 million that should be left after taxes.
A reminder that if you want to avoid being broke, you have to keep up the right mindset--whether you're an NFL player or a grad student!
