His testing numbers
Testing numbers
none yetNo testing numbers for Kasen yet. His family can add his 40, shuttle, jumps, bench and track times below, with proof.
How we know each number. Verified: a testing company or state meet result we matched to his name, class and date. Coach-confirmed: his coach said yes from a school email. Video-evidenced: a clip of the timer or tape that we watched. Self-reported, in grey: his family's word. Testing numbers here come only through this form.

His best-fitting offers first; pick any 4 of Kasen's 20 to compare. Green is the best in each row. Room counts the players at his spot with two or more years left. Players like him: up to five past recruits whose offer boards looked most like his and who signed at that school, from classes whose careers are over; a real season means 100+ passes, 50+ carries, 15+ catches, 25+ tackles, 3+ sacks or 2+ interceptions. Offensive linemen and defenders from classes before 2016 are not in that row: the box score does not count linemen's work and has no tackles before 2016. History, not a forecast for him. Green on the scheme row: it plays the front or the offense his role fits. How fit is made.

Past boards are offers at signing day; his is the board he holds today (Nov 12, 2026).
