Edwards, 6-foot-6 and 308 pounds, ceded the jumbo tight end role to Alec Anderson and has taken over at left guard, where McGovern lined up last year.
“I just think he’s a great player, overall,” McGovern said of Edwards. “He sees the game a lot of the same ways I do. He’s my right-hand man. He helps me with all the calls. He’s fit perfectly with this offensive line, and it’s really helped my transition to center go even smoother.”
