Terrell Davis says he's hyped that his former team, the Denver Broncos, signed Melvin Gordon ... telling TMZ Sports Gordon is a talented running back -- and BIG!
The L.A. Chargers clearly didn't think so ... they let the 215-pound RB go after 5 seasons -- giving the Broncos the opportunity to sign the 26-year-old to a 2-year deal worth $16 MIL last month.
"When you can get a guy as talented as Melvin, ya know you always would like to add that to your backfield," the former Broncos champ says.
