Forget the fact that Emmanuel Sanders said "Bronco Nation" instead of "Broncos Country," fellow receiver Demaryius Thomas didn't make the trip to Duke this year (that appears to be the case, anyway). Sanders was joined by Wes Welker, Bubba Caldwell, and Julius Thomas at Peyton Manning's annual Duke workout. Thomas' absence is likely injury-related (he separated his shoulder in the Super Bowl).
Update: Both ESPN's Jeff Legwold and CBS' Vic Lombardi have confirmed Demaryius Thomas is absent due to his shoulder injury. Update II: Legwold and Lombardi were wrong, Thomas is actually at Duke with his teammates.
