Here is a great reality check for all the people who think it would be a ridiculous notion to trade Darrelle Revis because he is the best CB in the league.
Wayne Gretzky was arguably the best hockey player to lace up skates. He was virtually untradeable given that fact.
Yet, the Oilers traded him for what amounted to being a bag of hockey pucks.
How many Stanley Cups did it get the Los Angeles Kings: 0
How many Stanley Cups did the Oilers win without Gretzky: 1
If Wayne Gretzky is tradeable, and a franchise can win without him, then I think people who are against trading Revis because he is the best CB in the league (not even the most valuable position on Defense, let alone the entire team), then I would suggest a rethink on being open to trading him is needed.
