DEION SANDERS RESPONDS TO CRITICISM OF LEAVING JACKSON STATE FOR COLORADO

The Pro Football Hall of Famer let his new team know Shedeur would be their quarterback in 2023, adding he would "have to earn it."

Speaking with the Buffaloes for the first time, Deion said he was "bringing [his] luggage with [him]. And it's Louis [Vuitton]," a reference to several of his Jackson State players joining him.
