McCollum is a 6-foot-2 corner with 4.33 speed, a 39.5-inch vertical and an 11-foot broad jump, a rare combination of length and explosion for the position. Sam Houston State used him in press and off-man, and he wins early with a long arm at the line and late with the speed to recover when a receiver stacks him.
Ball production was the calling card: 54 passes defensed and 13 interceptions across five seasons, including 17 breakups as a true freshman. The questions are technical rather than physical. He is grabby through the route stem, his hips can be stiff on sudden breaks underneath, and he tackles more like a man avoiding contact than one seeking it on run support.
Press-man and Cover-3 match defense that puts a long corner on the boundary and lets him jam receivers at the line rather than bailing at the snap.
Year 1: fourth corner and special teams while the technique catches up. Ceiling: full-time boundary starter against the opponent's big outside receiver.
A heavy trail-man scheme that asks him to mirror shifty slot receivers through option routes, where his hips and his hands both get exposed.
Give him a route tree that runs vertically and he is a problem.

Sam Houston State CB Zyon McCollum - Obscure Prospect Series
Technique breakdown of his jam, hip transition and tackling from the FCS film.
McCollum grew up in Galveston and went to Ball High, the same school as Mike Evans, committing to Sam Houston State alongside his identical twin brother Tristin. He started ten games as a true freshman in 2017 and intercepted three passes, the first Bearkat freshman with three or more picks since 1973.
He never stopped producing. First-team All-Southland in 2018, second-team in 2019, first-team again in the spring 2021 season that ended with an FCS national championship, then a fifth-year return that brought first-team All-WAC, third-team Associated Press All-America honors and invitations to both the Senior Bowl and the Shrine Bowl. Five seasons produced 56 games, 52 starts, 54 passes defensed, 13 interceptions and six forced fumbles.
The Combine turned a good small-school corner into a national name. At 6-foot-2 1/8 and 199 pounds he ran 4.33, jumped 39.5 inches and 11 feet, and posted a 6.48 three-cone, one of the best athletic profiles in the class at any position. Daniel Jeremiah ranked him the ninth corner on the board and most analysts projected round three or four. Tampa Bay traded a 2023 fourth-round pick to Jacksonville to move up and take him 157th, betting that FCS technique could be coached and this body could not.
- 01
Athletic profile
4.33 speed, a 39.5-inch vertical and an 11-foot broad jump at 6-foot-2, testing numbers that put him among the best athletes in the class.
- 02
Ball production
54 passes defensed and 13 interceptions in five seasons, including 17 breakups and three picks as a true freshman starter.
- 03
Length in press
uses his reach to disrupt releases at the line and stays attached down the sideline on vertical routes.
- 04
Recovery speed
the rare corner who can concede a step on a double move and still run the receiver down before the ball arrives.
- 05
Durability and experience
56 games and 52 starts over five seasons, with Senior Bowl and Shrine Bowl invitations confirming the résumé against better competition.
- 01
Technique at the top of routes
grabs and leans instead of playing through the hands, a habit that draws flags against NFL receivers and officials.
- 02
Hip fluidity
can be stiff redirecting on sharp in-breaking and comeback routes, which shows more against quickness than against speed.
- 03
Tackling
inconsistent as a run defender, taking angles that let ball carriers through the edge rather than squaring up and finishing.
- 04
Level of competition
Southland and WAC receivers did not test his technique the way NFL starters would, so the projection rested heavily on testing.

Season lines come from Tampa Bay's official player biography, which reproduces Sam Houston State's numbers; the 2020 season was played in the spring of 2021 and ended with an FCS national championship. Passes defensed (54), interceptions (13) and forced fumbles (6) sum exactly to the published career totals. Tackles do not: the seasons add to 205 while the bio's career line reads 145, a figure that appears to count solo tackles only, so 205 is used for the career row and the difference is flagged here. Games for 2021 and starts for three seasons are not published individually and are left blank rather than derived. Tackles for loss are published only as a career figure.
A dash means the figure is not published by a source we trust — never a zero we invented.
Multi-year outside starter with flashes and penalties who earns a real second contract without ever being a shutdown corner.
Day 3 corner with rare size and speed who starts immediately and makes a Pro Bowl on ball production.
Long corner whose grabby technique forces a move inside and a career as a rotational defensive back.
Everything above is the pre-draft evaluation. This section is what actually happened — updated year over year.
The traits won. McCollum was inactive the first four games of his rookie year with a hamstring injury and finished 2022 with 24 tackles in 13 games, then grew into a rotational role in 2023 with 68 tackles, nine passes defensed and two forced fumbles across 17 games and nine starts. When Carlton Davis left in 2024 he won the job outright, started all 17 games and posted 82 tackles, a career-high 17 passes defensed, two interceptions and a fumble recovery, grading 54th of 222 qualifying corners at Pro Football Focus.
Tampa Bay paid him like a starter. In September 2025 the Buccaneers signed him to a three-year, $48 million extension with $35.4 million guaranteed, and he made 13 starts with an interception and six breakups before a hip injury put him on injured reserve in December. Through five seasons he has 62 games, 44 starts and 35 passes defensed, all for the team that traded up to get him. A fifth-round pick who becomes a paid starting outside corner is exactly the outcome that justifies spending future capital on a small-school athlete.
