If Calvin really wanted out of Detroit he could have gotten out.
So could have Barry Sanders.
In one way it sucks because he's still a great receiver that could have either contributed to the Lions, or if he wanted out the Lions could have gotten maybe a 3rd rounder for.
In the other way, it's good because that's a lot of cap space that just opened up for the Lions to go after free agents. Question now is what will Stafford be worth on the open market. Rumor is the Texans are so desperate for a franchise QB that they will likely be overpaying for that type of QB - as in multiple 1st, 2nd, and 3rd rounders over several years. Then it sounds like Jerry Jones is also interested in Stafford. Potential bidding war. Considering the Lions' new GM and another front office guy just came over from the Patriots, and the Patriots' way is to get as many draft picks as possible, Stafford may be gone as well.
The real question is, considering Martha Ford has already been on the record as saying she "really likes Jim Caldwell", and Quinn (the new Lions' GM) seemingly unquestioningly brought Caldwell back, has the Ford family already neutered Quinn? The Fords have been doing things "their way" since 1963. "Their way" has netted exactly 0 NFL Championships/Super Bowls since 1957.
