During the Jets' current five-game winning streak, their offense has surged.

This is a big reason why they control their playoff fate heading into Sunday's game at the Bills. If the 10-5 Jets win that one -- for their first six-game winning streak since 1998 -- then they will be in the playoffs.

PLUS: What Jets' Todd Bowles has gotten right and wrong in Year 1

The Jets have scored 38, 23, 30, 19, and 26 points over this five-game span. Their yardage totals: 411, 463, 439, 372, and 428.

The Jets have six games of 400-plus yards this season, and four have come in their past five contests.

Before this five-game winning streak, the Jets were averaging 351.2 yards this season. During the streak, they are averaging 422.6 yards.

Why the uptick in production?

You might recall that Jets coach Todd Bowles said after the loss in Houston, which immediately preceded this winning streak, that the Jets needed to get back to "algebra" -- and a more simplified approach -- on offense.

Here's how quarterback Ryan Fitzpatrick explained the simplification processes that offensive coordinator Chan Gailey undertook:

"It's been a lot of different things. It's not necessarily that we were trying to run different route combinations, but I think we were just trying to reinvent the wheel. We were putting people in a bunch of different positions and situations. I think that was hurting me more than helping me, just in terms of my decision making.

"We're still moving guys around and doing things, but more to what I'm comfortable with -- and still simplifying some of that stuff, even though a lot of the route combinations are the same and a lot of the plays are the same. With me and the way that I think about the game, I guess pre-snap, getting guys in certain positions that I'm comfortable with, is probably the best way to put it."

Fitzpatrick has 13 touchdown passes and one interception during the five-game winning streak, compared to 16 touchdowns and 11 picks in the first 10 games.

Yes, two of the Jets' games during this streak went to overtime, so they had more time to gain yards. But it's also worth noting that all of the Jets' points during the streak came from their offense -- and none from special teams or defense.

In fact, the Jets have zero touchdowns directly from their special teams or defense this season. The Jets' scoring average during this five-game winning streak: 27.2 points per game. Before the streak, it was 23.4 points per game this season.

Entering last Sunday's win over the Patriots, the Jets were 14th in the NFL in Football Outsiders' offensive DVOA. Coming out of the Week 11 loss in Houston, just before this winning streak began, the Jets were actually 16th. Not bad.

So their offense has been reasonably solid for most of the season -- a major change from recent years.

But the Jets did hit a lull during their 1-4 midseason skid. They averaged 21 points and 322.6 yards over that span, compared to 25.8 points and 379.8 yards during their 4-1 start.

Here's a boiled-down, by-the-numbers look at the ups and downs and ups for the Jets' offense this year:

First five games (4-1): 25.8 points per game, 379.8 yards per game

Next five games (1-4): 21 points per game, 322.6 yards per game

Next five games (5-0): 27.2 points per game, 422.6 yards per game
