The transformation in personality the receiver now hopes for officially had taken root, with the video serving as a motivational tool behind Lelie's entire preparation for training camp.
"It made me hungrier to want to get out here to show everybody I can do everything," he said.
First stop, weight room
Just as important, it convinced him he would have to get stronger to face that challenge.
The decision to hit the weight room hard coincided with the natural development of Lelie's 25-year- old body.
It yielded significant results, too, even if he never will mold himself into a hulking figure at a lanky 6-foot-3.
An example of the gains he made could be seen in the bench press. Whereas he previously could do a single repetition, or maybe two, lifting 225 pounds, this off-season he was doing three sets of 225 seven or eight times.
"He's worked his (expletive) off," Broncos quarterback Jake Plummer said.
Lelie also gained 5 pounds, bringing his weight to about 205.
"Honestly, this year he's grown up," fellow receiver Rod Smith said. "He just grew up as far as this business and as far as understanding what we expect and what he can get out of himself. And he knows he can get a little more."
More catches. More yardage.
More fired up.
