Detroit was losing Roy after the season anyways. And they get a first, third, and sixth round pick. I call that a win for them.
And I would venture to say that the towel was thrown in when they placed on Kitna on IR. I know, Kitna is not the best QB in the game... but he gives them (when healthy) a far better chance to win than either Orlovsky or Stanton. Of course, Detroit has far more issues than their QB, I just hope they don't go winless.
Calvin is still talented enough to get some catches and some touchdowns, hopefully. Of course, I own him in both fantasy leagues so I have to remain optimistic
A better discussion is when Owens is going to be let go by the Cowboys. Lots of rumors out there, I think there is a good chance he could be gone next off season at the earliest... or maybe after next year if the Cowboys don't win the Super Bowl next year.
