"He is not the biggest or the longest linebacker in the class, but he has spent five years wearing the green dot at two programs and arriving at the football before it was supposed to get there."Pre-draft read
Downhill weakside linebacker who spent five years as the green-dot communicator of two defenses, aligned mostly at WILL in nickel and stacked over the guard on early downs. His calling card is trigger: he reads the guard's helmet, commits, and arrives on the ball carrier's numbers with a compact wrap-and-drive finish.
Against the pass he is a zone-drop and match player who carries verticals through the hook and passes them off cleanly, and he was trusted as a green-dog and A-gap pressure piece. The split is honest: plus run defender first, functional coverage body second. The athletic ceiling is good, not rare; the separator is instant processing married to volume tackling.
One-gap 4-3 under / nickel 4-2-5 that lets linebackers run and keeps them clean behind penetrating three-techniques.
Year 1: four-phase special teams ace and third linebacker in base packages. Ceiling: full-time WILL starter who handles the green dot, plays 60-plus percent of snaps against 21 personnel and holds up in zone coverage.
A two-gap 3-4 that asks him to take on and hold pulling guards head-up, or a man-heavy sub defense that requires him to travel with backs and slots across the formation.
He needs a front that keeps offensive linemen off his body; give him grass and a key and he plays fast, cover him up and his frame becomes the problem.

49ers seventh-round pick Tatum Bethune's college highlights
Team-produced reel released after San Francisco selected him at pick 251.
Bethune is a five-year, two-program starter whose football identity was built on volume and communication. He arrived at UCF out of Miami Central, took over the middle by his sophomore year, then transferred to Florida State and immediately became the voice of Mike Norvell's defense. Two schools, two systems, same job: get everybody lined up and go make the tackle.
The production backs the tape. He piled up 339 career tackles across 61 games, including a 108-tackle season at UCF in 2021, and was a top-two tackler for the Seminoles in both Tallahassee years. He won the Monk Bonasorte Award in 2022 for the defensive player showing the most heart, then earned Third-Team All-ACC in 2023 leading a 13-0 regular-season defense in stops. The flags were profile more than performance: a shade over six foot, arms that get swallowed when linemen reach him clean, and eyes that chase action on misdirection.
The board treated him accordingly: a steady Day 3 grade, floated most often as a fifth-to-sixth-round core special teams linebacker with backup WILL upside. San Francisco taking him at 251 was less a reach than a value snag — a defense built on rangy, instinctive linebackers spending a nearly free pick on a five-year starter who could cover kicks on day one.
- 01
Trigger and downhill speed
He diagnoses run keys fast and drives on them, closing space before the offensive line can climb to the second level.
- 02
Volume tackler
339 career stops over 61 games at two programs; he consistently finds the ball and finishes with compact wrap-and-drive technique.
- 03
Blitz timing
Used as a green-dog and A-gap pressure piece who times the snap well and slips through creases to hit the quarterback's back shoulder.
- 04
Green-dot leadership
Held the communication role for both UCF and Florida State, getting the front seven aligned and adjusting checks without hesitation.
- 05
Special teams profile
Ran with core units in college and brings the speed, physicality and want-to that translate directly to an NFL coverage-team role.
- 01
Block deconstruction
Once an offensive lineman gets clean hands on his frame, he struggles to disengage and can get washed out of the gap entirely.
- 02
Eye discipline
He will chase action and overrun the ball on misdirection, cutbacks and boot fakes, taking himself out of otherwise sound fits.
- 03
Man coverage limits
Fluid enough in zone, but tight and grabby when asked to turn and carry a back or slot receiver across the field in true man.
- 04
Length and mass
At 6-1, 229 with short arms, he lacks the frame to consistently stack and shed against power run games at the NFL point of attack.

A dash means the figure is not published by a source we trust — never a zero we invented.
Late-round linebacker who wins on speed and special teams and holds up as an emergency starter.
Undersized, downhill WILL who outran his draft slot by processing fast and tackling in volume.
Core coverage-team linebacker whose defensive snaps stay situational for his whole career.
Everything above is the pre-draft evaluation. This section is what actually happened — updated year over year.
San Francisco used the 251st pick exactly the way you would expect. Bethune spent his rookie year in 2024 as a core special teams player, appearing in 11 games with seven combined tackles and almost no defensive snaps behind Fred Warner, Dre Greenlaw and De'Vondre Campbell. Then 2025 forced his hand. When Warner went down with a season-ending ankle injury in October, Bethune slid into the starting lineup and stayed there until an ankle problem of his own cost him a few games late. He finished with 37 solo tackles and a sack, posted multiple double-digit-tackle games against Tampa Bay, Atlanta, Houston and the Giants, and looked like a real NFL starter in the middle of a playoff defense. He is back on the 49ers' roster in 2026, healthy and cheap on year three of his rookie deal.
In hindsight this was one of the better late-round hits of the class. The scouting report held up almost line for line: the trigger and tackling volume traveled, the block deconstruction and man-coverage limits still show when offenses target him, and he is still not the guy you want covered up by a 330-pound center. But a 251st pick who becomes a competent full-season starter in an emergency, plays winning special teams the rest of the time, and costs nothing against the cap is exactly the return teams hunt for at the bottom of the seventh round.
Data note: Sacks 0.0 in 2019 and 2023 confirmed by career total of 7.5 (2020-2022). 2019 forced fumble unverified; career FF total of 2 per official bio.
