No. That's the contract they gave the player. And as he said, it further shows how poorly they've run the OL that they cut these guys before they even got close to getting their full contract.
Can you read? The article clearly says "What Did the Miami Dolphins Buy with $210 Million? " in the title. And then he says we didn't actually spend $210 million on these players when he claims "most of the contracts never reached their full maturity".
So what part of this contradiction do you not understand? It was clearly an embellishment of the facts in order to make a convoluted point.
