Please don't mention Csonka and Ricky in the same sentence. It's night and day.
Csonka brought us a SB win and he left because the structure of the league didn't allow any rights for the players to make a wage they deserved. That was before players made the money they do today for their efforts. There was no free agency.
Ricky walked away at the worst possible moment to inflict the most harm. He did so maliciously.
Their intent was radically different. Csonka needed to seize an opportunity to make financial security for his family. Ricky walked out on a hugh contract and intended to hurt everyone.
