Karsten Busch

Physical Profile

Listed at 6-3, 223 lbs. Taller than 71% and heavier than 81% of 2026 Linebacker prospects in the SEC Scouts database (207 with a listed size).

Play Style

Busch plays downhill and looks for contact. He triggers fast on run reads, attacks gaps instead of waiting and catches ball carriers from behind with good angles. From the edge he gets upfield and pressures the quarterback, which explains the 7 junior sacks. Inside, he fills his run gap aggressively and plays through contact. As a senior he was used more as a tackle machine (110 tackles, 10 TFL, only 1 sack), which points to a move toward an off-ball, second-level role. In coverage he currently plays better going forward than dropping back.

Strengths

• Pursuit and closing: evaluators single out his chase-down ability, pointing more to his angles than to raw speed. He rarely takes a bad path to the ball, which shows up in 110 senior tackles.
• Run fits and block destruction: he reads his keys quickly, stacks and sheds blockers with his hands and hits hard in the hole. His junior season (59 tackles, 12 TFL, 7 sacks) shows he wins at the point of attack instead of just cleaning up.
• Versatility and pressure value: at St. Xavier he played mostly as a 3-4 outside linebacker and also lined up inside off the ball. He shoots gaps well from both spots, so a coordinator can use him on pressures and simulated blitzes.
• Ball skills: as a two-way player he caught 13 passes for 274 yards and 5 TDs as a senior (21.1 yards per catch). His hands and ball tracking should help once he develops in coverage.

Areas to Improve

• Zone coverage: he has shown flashes dropping into zones but it isn't a strength yet. At Miami he'll need consistent depth, eye discipline and route recognition against spread offenses before he's an every-down player.
• Tackling technique: he is mostly a sound tackler but sometimes dives or leads with his head. That causes missed tackles against better athletes in space and risks targeting calls at the college level.
• Learning one position: splitting time between edge and off-ball roles, plus offense, means fewer reps as a full-time inside linebacker. Pre-snap diagnosis, communication and fitting against college run schemes will take time.

College Projection

He fits as an inside or weak-side linebacker in Corey Hetherman's defense at Miami. Hetherman is both defensive coordinator and linebackers coach, and he recruited Busch directly in the final days before signing. Expect special-teams snaps and rotational run-down reps in year one, with redshirt eligibility still available. The realistic timeline is to compete for a starting job by year 2 or 3 (2027-28), once his coverage and tackling technique catch up to his run-defense instincts. With Justin Edwards also in the class, the depth chart competition will be real. Early playing time is most likely on special teams and in heavy run-down packages.

NFL Outlook

He profiles as a possible mid-to-late-round (Day 3) NFL prospect if he develops as expected. The NFL wants his size, his tackling range and his pressure ability from multiple alignments. Whether he climbs higher depends almost entirely on coverage. Linebackers who can't carry backs and tight ends or run a reliable zone drop become two-down and special-teams players at the next level. If he becomes competent in coverage and adds 10-15 pounds with his speed intact, he has the tools of a starting NFL WILL or MIKE.

Best Fit

An aggressive, attacking 4-2-5 or multiple front, like Miami's under Hetherman, that lets its linebackers trigger downhill, run simulated pressures and play mostly spot-drop zone early on. Programs that value tough, physical linebackers who can blitz from inside and outside will get the most from him. Man-heavy schemes that put linebackers in space against slot receivers on every down are a worse early fit.
