Kirk established himself as one of the SEC's most dangerous playmakers in his first two seasons at College Station, catching 163 passes for 1,937 yards and 16 touchdowns. He also added five punt-return scores, making him a threat in multiple roles.
He impressed again in 2017, notching 71 receptions for 919 yards and 10 total touchdowns despite the Aggies' reliance on freshmen quarterbacks in Kellen Mond and Nick Starkel.
Kirk, to his credit, never let the pair's struggles affect his demeanor.
"He doesn't show it," his former high school coach, Jason Mohns, told Ben Baby of the Dallas Morning News in early November. "He doesn't complain about it. It'd be easy for guys to complain about it or whine about it and pout. You watch his body language during a game, he's not feeling sorry for himself. He's still a team guy."
Aggies head coach Kevin Sumlin concurred.
"He wants to be the best at what he does," he told Baby. "There's a lot of people who say that but don't back it up with their actions during the week. Probably the biggest compliment that I can give him is that he's done that."
As for his NFL prospects, Kirk is a strong candidate to be selected in the first round. November 20, B/R's Matt Miller listed him as the draft's fourth-best receiver and labeled him as its top slot option. It's hard to imagine Kirk would drop past the second round given his explosiveness and history of production.
At minimum, he projects as an excellent returner and solid third or fourth receiver. But his playmaking ability means his potential is much higher.
