Foolish interceptions, untimely penalties, and bewildering officiating has brought the Broncos to their first loss of the 2017 NFL season.

In a mistake frenzy afternoon, the Broncos made the Buffalo Bills of all teams look like an overly capable and competent football team while showing no signs of having a heartbeat themselves. It was indeed a surprising twist that after Denver absolutely embarrassed the Dallas Cowboys a mere week ago, they would completely lay an egg against a seemingly inferior Bills team.

But that is why we all love football — it’s ridiculously unpredictable.

Let’s take a look at four takeaways from the Broncos’ 26-18 loss to the Bills:

1. Trevor Siemian was abysmal at best

We didn’t really expect Trevor Siemian to continue to lead the NFL in passing touchdowns, did we?

Well, except for those like myself that started him in Daily Fantasy leagues like a total moron . . . but the rest of you didn’t truly expect it, right?

Siemian had been nearly inhuman thus far throughout the 2017 campaign on his way to throwing for 450 yards and six touchdowns through two games, but the Bills defense brought Siemian and the Denver offense back down to earth in a big way.

The national media and local media alike have always been very complimentary of the former Northwestern quarterback — especially over the last few weeks. He has been praised for his ability to avoid mistakes and daft decision making, and has impressed many with his strong arm and aptness to find targets through tight windows.

But the Denver quarterback looked lost and confused against the Bills secondary.

Siemian finished the afternoon by completing 24 of his 40 attempts for 259 yards, but produced two turnovers, one of which was unforgivable.

Down seven on the Buffalo 24-yard line, Siemian floated a ball towards the sidelines in what looked like a hybrid between a pass attempt and a throwaway. The floating duck fell into the hands of the Bills’ cornerback Tre’Davious White before Broncos wideout Bennie Fowler had even made his break.

Why on earth do you even make that throw?

It’s first down in a one score game, why not throw that sucker up towards the upper deck?

The pick was deflating and unnecessary.

Siemian will have to pick up his play and get back to what we saw from him the previous two weeks if this team is going to succeed.

2. The unsportsmanlike penalty on Von Miller was unbelievable

Midway through the fourth quarter in a seven point game, the Broncos defense managed to make a much needed play to get off the field and give the offense one more chance to tie the ball game up.

Bills quarterback Tyrod Taylor threw an incomplete pass after feeling tremendous pressure from Broncos’ linebacker Von Miller.

On his way to the sideline, Miller put out his hand to help up Taylor, but pulled the ol’ “too slow” routine that left the Buffalo quarterback on his back. Smiles were exchanged as the two players ran off the field just in time for the yellow hanky to make its appearance in the form of an “unsportsmanlike conduct” penalty on Miller.

The penalty ultimately kept the drive alive allowing the Bills to eat clock and tack on a late field goal to put the game away.

How on earth are you going to end a game on that?

Even the CBS broadcasters, Spero Dedes and Adam Archuletta, were left somewhat perplexed in the booth as to why the flag was thrown for the incident.

Miller, who took complete responsibility for the playful act that lead to the Denver defeat, has always been one of the more amusing players with his extracurricular activities.

But to throw a flag for something as trivial as this is the total definition of the National Football League.

The No Fun League strikes again.

3. Two feet… four feet… six feet.. what is a catch anymore?

The Broncos offense was certainly inept for most of the afternoon, but they showed glimpses of a passing game every once in a while.

One of those glimpses came on a well-executed 44-yard catch by Broncos’ wideout Emmanuel Sanders late in the second quarter. Sanders took no less than four steps before getting the ball poked out by White on his way to the ground.

The call was originally called a “catch” but was overturned after Bills coach Sean McDermott challenged the play.

The overturned call forced Denver to punt from their own six-yard line after an illegal motion penalty, and the short field enabled the Bills to kick a 49-yard field goal to tie the game at 10.

The only problem is that it seems that no one knows what a catch is anymore.

Is catching and controlling the ball for four steps not considered a catch?

Why is a knee considered “two feet,” but four feet is not considered “two feet”?

Is running with the ball not considered a “football move”. . . don’t you run in the game of football?

Why didn’t Rose let Jack lay on the floating door after the Titanic sank? There was obviously room for two.

These are questions that we will all inevitably take to our graves.

4. The athletic ability of Tyrod Taylor brought the ‘No Fly Zone’ back to earth

The Broncos obviously went into Buffalo with the knowledge of how good Taylor can be. In fact, Denver went after the former Virginia Tech quarterback back in 2015, but Taylor ultimately turned the Broncos down for an opportunity to start in Buffalo.

Taylor showed just how talented he is against the Broncos’ secondary on his way to completing 20 of his 26 pass attempts for 213 yards and two touchdowns. His 126 quarterback rating is the highest the ‘No Fly Zone’ has given up this season and will likely remain close to the top all year.

Not only was Taylor dynamic in his ability to avoid pressure and lengthen plays, but he was also tremendous when throwing the ball downfield and was able to connect on several big plays. He also orchestrated a well-executed five-play drive at the end of the first half to steal points before time expired. The seven-year veteran was tremendous this afternoon.

Let’s hope that the ‘No Fly Zone’ got this out of their system and that they are back to their former selves next week against the Derek Carr and the Oakland Raiders.
