Kelly still had two years left on his 5-year, $32.5 million contract, with an annual salary of $6.5 million, according to Spotrac.
That means the Eagles still owed Kelly about $13.4 million at the time he was let go.
If you want to play the math game, that means the Eagles will ultimately play Kelly $32.5 million for 26 wins in three seasons, or about $1.25 per win. That's pretty hefty.
