It is time for coach Kubiak to make a decision.

Any decision.

The Denver Broncos need to know who their starting quarterback is going to be when the Carolina Panthers come into town on September 8. It has been a fun four months pondering over the possible quarterback scenarios, but now it has just lost its buzz.

Both Mark Sanchez and Trevor Siemian might just be warming the seat for rookie quarterback Paxton Lynch, but a decision needs to be made for the here and now. This team needs to find continuity and harmony in their offense, but until a quarterback is officially named as the leader of the troops, they will lack cohesiveness.

With the abysmal and repugnant offensive performance that was showcased last season, the Broncos showed that they do not necessarily need Peyton Manning’s Star War numbers to succeed, but an offense that just will keep the clock rolling and avoid putting the defense in strenuous positions. Although he might never separate himself from likely the most memorable play in modern football known as “the buttfumble,” Sanchez is the man for the job.

Here are three reasons why.

Sanchez gives the Broncos veteran leadership.

Let’s face it.

Neither Sanchez or Siemian have been able to separate themselves from the pack. Sure, you can use the “eye test,” but only 35 percent of adults have perfect vision and I don’t like those odds. Statistically, they are nearly identical this preseason. Sanchez has completed 67 percent of his passes for 219 yards and a touchdown, while Siemian has completed 65 percent of his passes for 163 yards but has yet to complete a touchdown.

Both quarterbacks have also turned the ball over. Sanchez fumbled twice deep within the San Francisco side of the field and was picked off by Bears’ linebacker Jerrell Freeman after an athletically played tipped pass by cornerback Bryce Callahan. Siemian was read like a book and intercepted by 49ers’ safety Eric Reid which was taken to the house for a 42-yard touchdown.

With both quarterbacks being of similar talent and ability, I think the nod goes to the veteran Sanchez. He has played in 75 games and has seven years of NFL experience under his belt. Siemian, on the other hand, has played in only one NFL game in which he took a snap to kneel the ball before halftime when an injured Brock Osweiler was in the locker room. It may officially count as a game played, but as far as I am concerned he has not played a game in the NFL.

The Broncos current roster has an embarrassment of riches and is poised to make another Super Bowl run. This is not a rebuilding or teaching season. If the Broncos are going to trot a quarterback out on the field with no NFL experience, it might as well be Lynch.

Sanchez gives the Broncos the best chance at winning this season.

Plain and simple.

Confidence is a fragile thing.

With the lack of separation by Siemian and Sanchez, the rookie out of Memphis has played himself into at least starting consideration. Lynch has completed 64 percent of his passes for 187 yards and two touchdowns. He might be consistently playing against opposing back-ups, but its important to remember that he is also playing with reserves as well. Throwing the ball to DeVier Posey and Henry Krueger-Coble can be a little different than Demaryius Thomas and Virgil Green. Michael Schofield has also done his very best to give Lynch first-hand experience at being perpetually pressured. Through two preseason games, Lynch has worn the jersey well and has definitely shown that he has the talent and ability worth taking in the first round.

But confidence is a fragile thing.

Trent Dilfer, a sixth overall pick in the 1994 NFL draft, was given the starting job in Tampa Bay his rookie season after the Buccaneers shipped off starter Craig Erickson. After struggling through the rest of the 1994 season, Dilfer had an atrocious 1995 season in which he threw four touchdowns and 18 interceptions.

“You have so many failures early on that you lose your confidence,” he told ESPN. “You start playing with that evil demon on your shoulders saying, ‘Don’t, don’t, don’t, don’t.”

Dilfer had a long NFL career, but never developed into the quarterback that analysts had projected and ultimately spent a majority of his career as a back-up. We can only speculate, but things might have worked out differently if Dilfer was groomed and ready before he was thrown to the wolves.

The Broncos current kicker Brandon McManus is another example of what a lack of confidence can do. His 2014 season seemed to be a constant mental struggle as he only posted a 69 percent field goal success rate. It was clear that he lost confidence in himself, and was replaced by placekicker Connor Barth after the team seemingly lost confidence in him as well.

He showcased in 2015 that he clearly has the talent to be one of the best kickers in the NFL by drilling home 86 percent of his kicks, including going five for seven on attempts over 50 yards. But when things aren’t right between the ears it is tough to transfer talent into success.

This is not what the Broncos want for Lynch. They have invested a lot into him and to start his NFL career before he is ready could hinder his growth as a quarterback. He has clearly already shown that he has the tools to succeed in this league, but a talent without the head for it doesn’t go a long way.

Lynch is the future, but not the now.

A midseason switch is a viable option with Sanchez.

Despite which quarterback is spinning the pigskin, the Broncos are likely to be a top-tier team this season. But trading a helmet for a clipboard is much easier to do with Sanchez if for some odd reason the Broncos start to struggle offensively.

That is not necessarily the case with Lynch. Once the Broncos choose to go in that direction, there is no turning back. Rain or shine, this top notch roster would be forced to grin and bear it.

However, if Sanchez starts to struggle mightily, the Broncos coaching staff has an out knowing that Siemian and Lynch are possible alternatives. He can be replaced very easily with another quarterback and no one will blink and eye.

Preseason reps are important, and until coach Kubiak decides on a starting quarterback, the chemistry and progression of the Broncos will be hampered. A decision needs to be made, and a decision needs to be made now.

Give Sanchez the ball, and let this team go to work.
