Von Miller might be out for the Minnesota game. That will hurt. He's as important as any player on the Broncos.
Sprig you make all excellent points...I'm not saying the Broncos make the playoffs, what I am saying that IF they do they will be a fearsome team to go up against because that will have meant that at the least they went 8-3, 9-2 to end the season which is pretty dang hot and if they are to win those tougher games against the Bears and NE then it will have shown they can hang.
Regarding comebacks, the Broncos aren't suited well to come from 3 scores back, but who is?
The whole Broncos game plan prevents getting that far behind in the first place. Ball control, field position, etc. If that plan fails like against Detroit they can obviously get blown out...but that can be said for almost any team whose game plan fails in a particular game. Can the Saints win without the pass? Can the Steelers win if they gave up 200 yards rushing, for example?
