Bottom Line
UDFA tight end with a 9.2 RAS lands behind Travis Kelce, Noah Gray, and Jared Wiley on a Chiefs depth chart with zero rookie-year runway. Hard pass in dynasty drafts; monitor the practice squad only.
Team Fit & Opportunity
Kansas City is the worst possible landing spot for a developmental TE. Kelce remains the WR-equivalent target hog when healthy, Noah Gray is signed through his prime as the in-line/move chess piece, and Jared Wiley is the front office's own 2024 4th-round developmental swing. Gyllenborg is TE4 at best, TE5 if Briningstool gets healthy, with only 30 vacated targets in the room and Andy Reid rarely deploying 13-personnel. Practice squad is the realistic Year-1 outcome.
Talent Profile
The athletic testing is the entire pitch: 4.6 at 250 with a 35.5" vert and 128" broad jump produces a 9.2 RAS — genuinely rare movement skills for the size. PFF's pre-draft profile flagged him as a developmental Y/F hybrid with functional hand usage on tape (the Brentnall route clip making rounds in April). But Wyoming production was modest, the route tree was limited, and going UDFA after late-Day-3 mock projections (No. 193–213 range) tells you the league saw a traits-over-tape projection. Athletic floor, undefined football ceiling.
Strengths
- Rare size-speed combo: 4.6 forty at 6'5"/250 is 90th-percentile movement; gives him a developmental archetype NFL teams chase.
- Explosive lower-half testing: 35.5" vert and 128" broad point to red-zone/seam-stretching upside if route polish arrives.
- Hand technique flashes: pre-draft tape circulated specifically for refined release work — unusual for a small-school traits prospect.
Concerns
- Depth chart is a brick wall: TE4 behind Kelce, Gray, and a 2024 4th-rounder the team is still developing — no path to snaps in 2026.
- UDFA capital: hit rate for UDFA tight ends becoming fantasy-relevant is sub-2%; mocked as late as pick 213 and still went undrafted.
- Small-school production gap: Mountain West usage didn't force teams to spend a pick — the traits didn't translate to dominant college tape.
Historical Comp Read
The athletic profile invites lazy comps to guys like Mike Gesicki or Darren Waller, but those players had either Day 2 capital (Gesicki) or a position-change runway and target vacuum (Waller in Oakland). The truer comp is the annual UDFA traits TE — your Pharaoh Brown, your Tommy Sweeney types — who stick on rosters as TE3 blockers and never sniff a target share. Athleticism alone doesn't beat zero opportunity.
Outlook
Year 1: practice squad or TE4 with zero offensive snaps that matter. Three-year arc requires Kelce retiring (likely by 2027), Gray departing in free agency, and Wiley failing to develop — a three-step parlay before Gyllenborg even competes for TE2 reps. Catalyst is a trade to a TE-needy roster; collapse trigger is being cut at final roster cuts. In dynasty, he's a deep-taxi-squad name to file away, not a draftable asset in any standard format.
