I put the offensive failure on McCoy.  McCoy's refusal to stay with the power running game which plays to the O-line strength really irritates me.  And McCoy's passing game seems to be mostly  run in high schools (but not nearly as good as top high school teams run).  McCoy succeeded with Manning because Manning rarely ran the play called by McCoy.  I've never understood how an OC with perhaps the worst view in the stadium can call a better play that a QB.

Broncos also do not have a single receiver whose speed threatens any NFL CB.
