Two words of friendly advice for anyone who's assuming a Vikings advantage against Mitchell Trubisky at Soldier Field on Monday night:

Chad Hutchinson.

Not that Vikings fans typically assume positive results, but for this word of caution, let's return to Dec. 5, 2004. The 7-4 Vikings were visiting the 4-7 Bears in a stadium where bad things tend to happen to good Vikings teams.

Hutchinson wasn't a rookie, but he hadn't started a game in two years when he got his first start as a Bear that day.

Purple people snickered. Then Chad posted a 115.0 passer rating while throwing for three touchdowns in a turnover-free 10-point victory.

And he never won another NFL game before disappearing with a 3-11 record.

Trubisky is even more of an unknown heading into his NFL starting debut. The No. 2 overall draft pick started only 13 games at North Carolina.

But …

If we've learned nothing else about the 2017 season through four weeks, it's this: Don't underestimate the rookies.

They're everywhere, from Deshaun Watson in Houston, to the head coaches of the jaw-dropping Bills and Rams, to kicker Harrison Butker, a no-name turned-Monday night hero in Kansas City.

" did a nice job," coach Andy Reid joked after his new kicker's 46-yard field goal gave the Chiefs the league's only 4-0 start. "Welcome to Kansas City."

And welcome to the NFL, guys.

Butker, who was signed off Carolina's practice squad last week, isn't even the first rookie kicker with a walkoff winner. Philly's Jake Elliott was even carried off the field after nailing a 61-yarder against the Giants.

Among rookie head coaches, the young McSeans have it. The Rams have 31-year-old offensive mind Sean McVay, while the Bills have 43-year-old defensive mind Sean McDermott.

McVay's Rams lead the league in scoring (35.5) and are the surprise team of the NFC, if not the NFL. McDermott's Bills lead the league in scoring defense (13.5) and are the talk of the AFC, if not the NFL.

At quarterback, Watson is saving the job of Bill O'Brien, the coach who didn't think Watson was ready to start in Week 1. That opinion, of course, changed at halftime of Week 1.

Three weeks later, in just his third NFL start, Watson led the Texans to 57 points in a blowout of Tennessee. He also became the first rookie QB with four touchdowns passing and one rushing since Fran Tarkenton did it against the Bears in the first game in Vikings history back in 1961.

At running back, Kareem Hunt went from little-known third-rounder from Toledo to the engine that's driving the Chiefs' momentum. Dalvin Cook was doing the same with the Vikings before tearing his left ACL, but the team's new lead back will be running behind a much-improved offensive line led by rookie center Pat Elflein.

In Chicago, Tarik Cohen looks like a young Darren Sproles. In New Orleans, Alvin Kamara, a running back, just had 10 catches for 71 yards, while another rookie, Marshon Lattimore, continues to start on a surprising Saints defense that pitched its first shutout since 2012.

Jacksonville is 2-2 in part because of rookie running back Leonard Fournette. The Jets just beat the Jaguars to reach 2-2 as rookie Elijah McGuire posted 131 yards and a touchdown from scrimmage.

Defensively, Colts rookie safety Malik Hooker is tied for the league lead in interceptions with three. Meanwhile, Buffalo rookie starting cornerback Tre'Davious White returned a fumble 52 yards for a touchdown and the deciding points in an upset in Atlanta.

All this while the top two picks in the draft — Browns defensive end Myles Garrett and Trubisky — have yet to do anything. Garrett might return from an ankle injury to face the Jets this week. And Trubisky already has been named the starter against the Vikings.

Will the draft's top two players bring more magic to the rookie class? That's a lot to ask, but in the name of Chad Hutchinson, don't rule anything out when it comes to the Vikings at Soldier Field.
