Careful Mitch, I remember when I suggested trading CJ and had the wrath of the board come down on me. Seems most people would rather watch a single superstar earn individual achievements than to trade that superstar to get the pieces needed for a team to compete for the Super Bowl.
Personally, I would trade Barry Sanders (in his day) or CJ AND Suh AND Stafford and anyone else I had to in order to create a Super Bowl Champion team. Individual players can be extremely fun to watch, but that is nothing compared to watching your team hoist the championship trophy. People have their priorities screwed up.
Granted there is no guarantees and the Lions could make trades and still end up not making the playoffs because, well, it's the Lions. Still, trading CJ, Suh, and Stafford would free up a ton of $$$, but you never know if the players you get will be worth a damn, so I get that side of the argument. Just tired of having all that money tied up when they could trade and get more depth for less money, freeing up money to get even better players and more depth.
