The All-Pro pass rusher did just that on Tuesday, wearing a full Bulls road uniform while with his family on Christmas. Mack sported a No. 52 jersey with his name on the back as he walked through a house and showed off his shooting form.
He then picked up a basketball and walked into an in-home court, doing some between-the-legs dribbles before drilling a jump shot.
"Looking great! Khalil Mack's got game," the Bulls wrote on social media, including the video.
"Even Khalil Mack got a Khalil Mack jersey for Christmas," the Bears wrote on a post of the footage.
The video was initially posted by Mack's brother, Ledarius Mack. Ledarius posted 16 tackles, 2.5 tackles for a loss, two sacks and a forced fumble last season for the University at Buffalo.
Khalil, 27, has 12.5 sacks, 47 tackles, a league-high six forced fumbles, an interception for a touchdown and two fumble recoveries in 13 games this season. The 2016 Defensive Player of the Year is a two-time All-Pro who was selected to his fourth Pro Bowl in 2018.
The 6-foot-3, 252-pound defender also played basketball while attending Fort Pierce Westwood High School in Fort Pierce, Fla., before fully turning his attention to the gridiron.
