Former Philadelphia Eagles great Jason Kelce is not a fan of the jersey numbers that defensive players can now wear.Entering the 2021 season, the NFL expanded the jersey numbers that were available to certain position groups. Kelce yearns for the days when he could look at a jersey number and know which position a guy played."I like looking at a jersey and knowing without f---ing knowing the guy what position that guy played. There was something about the number signifying the position you played," Kelce said during a recent episode of "New Heights."CLICK HERE FOR MORE SPORTS COVERAGE ON FOXNEWS.COM"I f---ing hate that the NFL changed the rule for defensive linemen. I used to love these iconic numbers that defensive ends used to wear, linebackers used to wear. Now, I see a (defensive end) and hes wearing No. 1 or No. 11."I shouldnt be calling out No. 11. Hes a f---ing good player," Kelce said, referring to Micah Parsons.Defensive linemen are still restricted to Nos. 5079 and 9099, but linebackers who line up on the line of scrimmage were given more options with their jersey numbers.

Like, wear No. f---ing 98 or something like that. Like, Im not into this. If youre a big body, youre playing the line of scrimmage, you have a big f---ing number. I dont want to see this skinny f---ing number bulls---."Defensive backs were previously restricted to Nos. 20-49 but now can wear Nos. 0-49."I dont like that now the numbers mean nothing on defense.
