The 2018 AFC championship game is just three days away! This year’s edition is a matchup for one team that has “been there and done that” against the new kids on the block. A true David vs. Goliath matchup. The New England Patriots are making their seventh straight trip to the AFC title game while the Jacksonville Jaguars are here for the first time in nearly 20 years!

Patriots' defense a big key

Defense! Defense! That is what most NFL fans think of when they think of the Jacksonville Jaguars. While the Jags do have one of the best defenses in the league, many fans forget that the Patriots' defense is pretty darn good as well.

In fact, no team has been tougher to score against than New England since October 1.

After the Patriots were embarrassed on opening night when they gave up 42 points to the Kansas City Chiefs, defensive coordinator Matt Patricia tightened the reins in a big way. After shaking off the cobwebs, the Patriots have been the toughest defense to score against over the past 14 weeks in the NFL.

Jaguars confident

The Jacksonville Jaguars were not given much of a chance to beat the Pittsburgh Steelers last week.

The Jags proved the critics wrong. Now for Jacksonville, things will get even tougher when they travel to Gillette Stadium for the AFC Championship game. The Patriots hardly ever lose at home. As in ever! Since 2010, New England has lost nine home games, compiling an insane 55-9 home mark.

The Jaguars don't care about records, Tom Brady or the legend of Bill Belichick -- they just want to win one more football game and shock the world by making it to Super Bowl 52.

They are young, brash and a bit cocky -- but they can back it up. Now, the question is: How will the Jags perform under the biggest spotlight of the season to date this weekend?

Vegas odds, prediction, game info

While the New England Patriots are a huge favorite in Sunday's AFC championship game, many experts believe that the Jaguars have a great chance of pulling off the upset win.

I don't.

If Jacksonville can do something that only nine teams have been able to do over the past eight seasons, then they more than deserve the trip to the big game in two weeks. The Jags won't be posting 40 points like they did last week against the Steelers. In fact, I think this game will be on the lower scoring side.

Prediction: Patriots 27, Jags 16
