Barkley's No. 26 jersey has been the NFL's top seller this week and for the last 30 days, according to DICK'S Sporting Goods Jersey Report.
The second overall pick of the 2018 NFL Draft even posted his first victory over an NFL East rival, with Philadelphia Eagles quarterback Carson Wentz -- who was last season's top seller -- now relegated to second in that regard.
Chicago Bears quarterback Mitchell Trubisky is ranked sixth, followed by New England Patriots quarterback Tom Brady, New York Jets rookie quarterback Sam Darnold, Cleveland Browns rookie quarterback Baker Mayfield and Giants wide receiver Odell Beckham Jr.
Optimism has been elevated as it relates to Barkley, who rushed 217 times for 1,271 yards and 18 touchdowns last season with Penn State, including a 92-yarder in a Fiesta Bowl victory over Washington. He also caught 54 passes for 632 yards and two scores, as well as returning two kickoffs for touchdowns.
The 6-foot-3, 233-pound Barkley lit up the 2018 NFL Combine with a spectacular workout, registering a 4.40 40-yard dash, a 41-inch vertical jump and 29 reps on the bench press.
