Just four teams remain on the road to the Super Bowl, which means the other 28 clubs already have their sights set on the offseason.

While free agency will give teams a chance to add key veterans at need areas, the draft is where true team-building takes place. This year’s event offers deep units at multiple positions, including a quarterback group that could give us six first-rounders for the first time since the historic 1983 class.

Monday was the deadline for this year’s underclassmen to declare for the 2018 draft, and over 100 prospects have chosen to make the early jump to the pros. While some big names are headed back to school for another season, this year’s draft is still loaded with star power.

It’s also all-star season for this year’s draft class, as the East-West Shrine Game and Senior Bowl will take place over the next two weeks, giving some of the top players another chance to prove their mettle against strong competition.

With the conference title games on the horizon, here’s an updated look at how the first four rounds of the 2018 NFL draft could go down.

FIRST ROUND

If new general manager John Dorsey is going to hit the reset button at quarterback, Rosen makes the most sense. He’s got his flaws, but Rosen’s the most pro-ready passer in this year’s class.

There’s little doubt the Giants need to use this rare opportunity and use the No. 2 pick on an eventual successor for Eli Manning. But which passer should it be? Darnold’s 2017 campaign has been a roller-coaster, but if he declares, his physical tools and upside are through the roof.

There are much bigger needs on defense for the Colts, but with an offensive coach like Josh McDaniels expected to take the reins, it wouldn’t be shocking if a rare talent like Barkley was simply too tempting to pass up.

With Barkley off the board and a new quarterback already in the mix, the Browns now focus their attention on their glaring need for a difference-maker in the secondary. Fitzpatrick’s versatility will make him a dangerous defensive weapon at the next level.

The Paxton Lynch experiment looks like a flop at this point, and the Broncos should strongly consider using their top-10 pick to swing away on another potential franchise quarterback. Allen is still extremely raw, but it wouldn’t surprise me if John Elway simply couldn’t resist his arm talent and upside.

No team needs a franchise quarterback as badly as the Jets, but this year’s deep class should give them a chance to find one here. What Mayfield lacks in ideal size, he makes up for in just about every other area of his game.

Quenton Nelson would be a strong option here, but Tampa Bay’s biggest need is bolstering their lackluster pass rush. Chubb is a top-five player in this draft, making him a steal at this pick and a perfect fit for what’s ailing the Bucs defense.

Mitchell Trubisky should have a lot more fun with the offensively minded Matt Nagy as his new head coach, but general manager Ryan Pace needs to find him some weapons this offseason. Ridley’s explosiveness and big-play ability is exactly what their young quarterback needs to take the next step in his development.

They stole their new franchise quarterback from the defending Super Bowl champs, and now it’s time to make sure he’s protected. Nelson may be the most complete play in this entire class, with the athleticism, physicality and attitude any team would love up front. He’s an absolute steal here.

Every level of this defense needs help, so this pick is about finding the best value. A top-five talent in this year’s class, Smith is a huge steal here, bringing an incredible blend of speed, athleticism, physicality and intensity the Raiders desperately need.
