Of course it's possible.  After NE, there's no reason to think that DEN isn't right there in the mix with OAK, PIT, and KC as the 2nd best team in the AFC.  So much depends on injuries and breaks though.  Fine line between being 9-7 and out of the playoffs (like last year) vs winning a close division with 10 or 11 wins.  Or going 12-4 and being the #1 seed as they were in 2015 en route to being SB champs.  

Something unexpected would likely need to take place with NE to get past them though.  Every team is just one season-ending injury to a great player away from having their season ruined.  So ya never know. 

I think it's certainly possible DEN could win 2 or 3 more games than they did last year.  Not saying I EXPECT it, but there's certainly a fair chance.  People were writing us off going into (and even during) 2015 as well, knowing that Peyton was fading fast.  We got the last laugh that year though.
