Indianapolis Colts coach Frank Reich challenged his players to show everyone they were more than just a playoff contender.

Saturday's impressive victory over New England proved the Colts were postseason worthy.

Now comes the hard part — doing it each of the next two weeks against foes with playoff hopes.

“There’s a lot of belief and a lot of conviction in we have the guys, we have the coaches, we have the process," Reich said Sunday. “If that’s really true, then we’ll play our best football in November and December. We’ll keep getting better, we’ll learn from our mistakes, and we’ll play our best football in November and December."

The Colts certainly have been on top of their game lately.

Since starting 1-4, they've won seven of nine. Both losses came at home, in overtime to AFC South-leading Tennessee and in the final minute against defending Super Bowl champion Tampa Bay. Both also came after Indy blew second-half leads.

But if the Colts replicate what they did against New England over the next two weeks, at Arizona and at home against Las Vegas, they will finish the regular season at Jacksonville with, perhaps, a playoff spot already locked up.

Indy rebounded from its sluggish start by following a proven formula.

Jonathan Taylor is running away with the league's rushing title. The closest contender to Taylor, who has 1,518 yards, is Joe Mixon of Cincinnati at 1,094. Taylor also leads the league with 19 touchdowns with the most recent being a 67-yard scoring run that sealed the 27-17 victory over the Patriots with 2:01 left.

Defensively, the Colts continue to lead the league with a plus-14 turnover margin and are tied with Dallas for the most takeaways (31).

Add an offensive line that has allowed 94 sacks since 2018, and a team gaining more confidence by the week and the Colts are primed to continue ascending.

All they must do now is demonstrate Saturday's victory was no fluke.

“We've got to win every one of these games," Reich said. “What we said in there was, ‘Hey, this is a great team win, but this counts for one. It counts for one, that’s it.' We've got to dial it back in and get ready to play."

WHAT’S WORKING

Punt blocks. Indy has blocked two punts in its past five games and linebacker E.J. Speed returned both for touchdowns. He's the first NFL player to achieve the feat since Baltimore safety Ed Reed in 2003 — and there are still three games remaining.

WHAT NEEDS HELP

Passing game. While Taylor has shown he can carry a hefty-sized workload, the Colts probably need Carson Wentz to be more effective through the air than he was against New England. He was 5 of 12 for 57 yards with one TD and one interception Saturday.

STOCK UP

Taylor. The second-year running back has topped the 100-yard mark eight times in 11 games and showed just how dynamic he can be Saturday. If Taylor has a scoring run in his 12th consecutive game Saturday, he'll break Lenny Moore's franchise record. He needs two total TDs to break the Hall of Famer's single-season franchise mark (20), which was set in 1964.

STOCK DOWN

Michael Pittman Jr. His productivity has been fine. But after Pats safety Kyle Dugger ripped off Pittman's helmet, the two were involved in a scuffle that led to the ejection of both. Without Pittman, Indy struggled to preserve the 20-0 lead it built before he was tossed. Pittman is Indy's top receiver and he can't afford to lose his composure.

INJURIES

Starting center Ryan Kelly missed the Houston game because of a positive COVID-19 test and the Patriots game because of a personal matter. He's likely to return next weekend at Arizona. Safety Andrew Sendejo has gone into the concussion protocol and his status will be determined later this week.

KEY NUMBER

Five. After winning five of their past six and getting some help around the AFC, the Colts enter Week 16 with the No. 5 position in the conference playoff chase.

NEXT STEPS

The Colts' short-handed secondary has had trouble against some of the league's top quarterbacks. Expect Cardinals quarterback Kyler Murray and productive running back James Conner to test Indy's pass defense. If the Colts defense holds up, it would be another big step.
