McClellan is a 6-foot-4, 313-pound lineman who can clog the interior and rush the passer, offering depth behind nose tackle D.J. Jones and behind defensive end Zach Allen.
The Missouri product began his college career at Florida before transferring to the Tigers, where his production jumped. In 2024 he appeared in 13 games with 9 starts, posting 2.5 sacks and 5.5 tackles for a loss, plus 2 pass breakups and 1 forced fumble. In 2025, he again played 13 games with 12 starts, compiling 48 tackles, 8 TFLs and a career-best 6.0 sacks.
Draft analysts view McClellan as a mid-round prospect, typically projecting him to come off the board in the 4th or 5th round. Evaluations highlight his solid build and ability to win with strong hands, but note he isn’t a natural knee-bender and must improve his take-on technique and hand usage to maximize consistency as a run defender and interior rusher. He’s viewed as a potential backup nose tackle in an even-front scheme.
The Broncos already boast a dominant pass rush, led by Nik Bonitto, All-Pro Zach Allen, and Jonathon Cooper, with the unit leading the league in sacks in recent seasons. They’ve invested heavily on the front, creating a scenario where a cost-controlled rookie like McClellan could slot in as rotational depth behind Jones and Allen, potentially replacing aging veteran depth with a longer-term, rookie-contract option.
