Kevin Curtis has left Allen Park without a signed deal.  As I reported, the Lions agreed to a deal as far as length and amount of money, the issue was how much was going to be guaranteed.
That is a huge issue in the NFL that some people don’t get is that contracts really are not necessarily guaranteed.  Curtis has an offer on the table with the Vikings, and it will come down to whether or not he wants to go to Detroit where his best friend (Mike Furrey) and favorite coach (Mike Martz) reside. 
I think it is about a 60% chance that the Lions get this done.  I know that his heart is here and that has to help.
