Cleveland Browns fans are clearly ready for the 2019 NFL season.

Fanatics shared the sales numbers of its top-selling NFL jerseys from this preseason, and quarterback Baker Mayfield came in at No. 1. What's more, teammate Odell Beckham Jr., his go-to option in the passing attack, was No. 7.

Kansas City Chiefs quarterback Patrick Mahomes, Chicago Bears pass-rusher Khalil Mack, New England Patriots quarterback Tom Brady and New York Giants running back Saquon Barkley rounded out the top five.

It is no wonder why so many Browns fans have bought jerseys this preseason.

The team went 7-8-1 during the 2018 campaign, which was its best record since 2007. Mayfield immediately turned things around, coming into a game against the New York Jets in Week 3 and directing a comeback win. Last year's No. 1 overall draft pick threw for 3,725 yards and 27 touchdowns.

Now Mayfield has a three-time Pro Bowler as a No. 1 option in Beckham, who figures to not only dazzle on his own but also open up the field for the likes of Jarvis Landry, David Njoku and Nick Chubb.

A Cleveland playoff appearance for the first time since the 2002 campaign is realistic, and Browns fans have geared up for even a potential AFC North title.

Elsewhere, Mahomes' place on the list is not surprising as the reigning league MVP, and Mack is the face of arguably the league's best defense in a major market.

It is a testament to Brady's greatness that he is still on the top five of this list at 42 years old. Logic dictates many Patriots fans who wanted his jersey would have already owned one before this preseason, but another Super Bowl ring probably helped result in more sales.
