A lot has been made about Marvin Harrison Jr.'s offseason body transformation. The first-rounder went from 209 pounds to 220 pounds, adding 11 pounds of muscle.
However, Harrison's weight change wasn't the most drastic on the team. It wasn't even the biggest fluctuation in the wide receiver room.
That distinction belongs to [Xavier Weaver](/team/players-roster/xavier-weaver/), who went from 169 pounds to 185 pounds.
"When I had that (shoulder) surgery, I lost a lot of weight," the wide receiver said. "Knowing that we play in a physical sport with a lot of grown men, I know I had to put on weight. I really had no option, no choice."
That 16-pound difference, similar to Harrison, hasn't impacted Weaver's speed. His quickness was put to the test in the 20-17 preseason victory over the Chiefs on Saturday. During the Cardinals' 79-yard drive to close out the first half, Weaver had a 13-yard catch, drew a 24-yard pass interference call, and then finished with a contested one-yard touchdown reception.
"I feel (defensive backs) panicking sometimes when they got to be in a certain spot," Weaver said. "With the speed that we bring on offense, it definitely brings something different to the defense with different looks and stuff like that, so I definitely see certain people panic to try and get to a certain position."
Deep threats like Weaver can be a matchup nightmare for cornerbacks. Coach Jonathan Gannon, a defensive backs coach by trade, noted secondaries play differently when they are "fearful of a guy running by you and hitting a home run."
