Khalil Mack has been with the Bears for less than a week, and No. 52 jerseys are already hitting the streets of Chicago.

Fans are all in on the new star pass-rusher, and they’re showing it with their wallets. Bears Mack jerseys are the fifth top-selling jersey in the NFL this preseason, according to Fanatics.

It helps that he’s locked in to a six-year contract that made him the highest-paid defensive player in NFL history. Bears fans can buy his jersey knowing he’s going to be around for a while and knowing he’s going to be one of the best edge rushers in franchise history.

Mack might be the most talented player on the team the minute he steps onto the field. He’s a bona fide superstar and the new face of the defense, at least until Roquan Smith takes over in the middle.

If Mack jerseys are selling this fast, then Soldier Field should be littered with No. 52 jerseys by Week 2 when the Bears face the Seattle Seahawks in the home opener.
