On Sunday, the Pittsburgh Steelers beat the Denver Broncos and while the final score of 13-6 indicated a close game, the Steelers were in control for the bulk of it and a late pair of field goals by Denver kept things tight.

Here are our five big takeaways from the game.

Justin Fields doesn't look comfortable

I am in no way going after Justin Fields here. Personally I think he's done enough to keep the starting job. But for a player as athletic as he is, he does not look comfortable on designed runs.

Run game was impressive

The tandem of Jaylen Warren and Najee Harris did exactly what you want from them. The two as sort of co-starters combined for 26 carries for 111 yards.

What happened to the secondary?

After only allowing 39 passing yards in the first half, the Steelers pass defense went to sleep in the second half. Fortunately, the lapse didn't have a serious impact on the outcome of the game, it is still worrisome.

Offensive line unrest

We are genuinely concerned that the Steelers might not get these issues at offensive tackle sorted out soon enough that it won't end up costing the team a win.

You are as good as your record

The Steelers team is a perfect example of a team that is doing just enough to win and not doing anything to lose. Is the team the most talented in the AFC North? Probably not but you are always as good as your record when it comes to the regular season.
