Manuel Ramirez is expected to open the season as the Broncos' starting center.
A converted guard, Ramirez has quietly graded out as a top-eight center in Pro Football Focus' 2013 preseason-game ratings. Ryan Lilja was signed as insurance, but has experienced recurring knee issues following offseason microfracture surgery. Ramirez has a big opportunity in the last year of his contract.
