Denver's defensive line is made up of 3 rookies and a guy they signed yeaterday.
San Diego's running game is better
San Diego's offensive line is better.
San Diego's linebackers are better.
The only positions where Denver gets an edge are defensive backs (huge edge) and #1 WR. Otherwise, San Diego's talent wipes Denver's out.
Plus, the majority of their team has been together now 3-4 years. A unit that talented and that cohesive will win in spite of Norv Turner's coaching.
Well, from September through December anyway.
