Reasons of the Broncos' 2016 struggle

Disappointing 2016 season for the Denver Broncos champions, called to defend the title but only able to win 9 games and also fail the minimum goal of the playoffs. Failure landing Broncos to the playoffs is due throughout the offense as the defense has also played this season at the highest levels both contri races that against the steps. The most important reason of all why the offense was completely unable to provide an average adjusted points to a pretender to the title is definitely the pick of Peyton Manning that left a hole in the important role that no one will ever be able to cover, Manning fact in my opinion the best quarterback of all time but not more powerful as two years ago was able to handle the attack as a coach, read situations, creating big play and give some confidence that this year is failure. Siemian despite all the criticism towards Manning and the doubts about its value in the last campaign has proven much lower and inadequate despite the more than valid group of receivers at his disposal. In fact, the rookie quarterback Denver has made only 18 TD passes throughout this season that sound even worse counting the 10 intercepts, my question is why coack Kubiak did not choose to run for cover by inserting the other rookie Paxton Lynch? Another major problem that has plagued the attack of the Broncos was the severe injury to his right meniscus runnign back CJ Anderson had to leave the field against the Texans and not making the most return for the rest of the season. Anderson was a key player for the Broncos the last two seasons providing power strokes among the tackle of good reads blocks able to give him some big play, its importance this year was still higher as the help that was to provide Siemian taking away weight and providing a good yardaggio able to not force a third and long situations. Devontae Booker his replacement has not been able to equalize the contribution of Anderson and more was the author of three fumble that cost dear to the team of Colorado. As for the line of attack I would not give him enough although a lot has been rejuvenated over the last two years with heavy departures as: LT Ryan Clady, Orlando Franklin LG / RT and RG Luis Vasquez. Youth like Matt Paradis C and Max Garcia RG look promising but still need to hone their skills in certain game situations before they can ensure continuous protection to the quarterback with effective blocks for the running game.
The generates John Elway manager over to invest to bring a good receiving tight end coach Kubiak will replace retiring after the last league game, the ideal person in my opinion would be the ex coach of the Chiefs and the current offensive coordinator of the Steelers saw the excellent work he made with the Pittsburgh offense making it one of the best in the NFL.
