Just a casual observation (and some of this is based on rumored contacts since no one really knows who contacted who) -

For all the supposed loyalty to Fox that players on the squad had, he has only been able to lure one former Panther out to Denver: Dante Rosario.  Overtures to Jeff King (signed with AZ), Derrick Landri (signed with PHI), DeAngelo Williams (re-signed, obviously),  and allegedly reached out to James Anderson (re-signed) and possibly Charles Johnson (re-signed with extreme prejudice). 

Frankly, it doesnt sound like anyone really wanted to go back and play for Fox, despite all the alleged support he had on the roster last year.  Moreover, it says a lot about how much (or little) stock players well familiar with his system put into it when they had the chance to join him in DEN.

Well, he can always call Jake if Tebow doesnt pan out........
