Xavier Tiller

Physical Profile

Listed 6-4/212 when he committed and 6-5/215 during his senior season, Tiller reported to Florida State at 6-5/226, the biggest of the Seminoles' three freshman tight ends, and 247Sports currently lists him at 239. That 14-plus-pound jump in one offseason is the single most important development in his profile: it moves him from an oversized wide receiver body toward a legitimate in-line frame. Evaluators graded his hands and wingspan as already plus for an NFL tight end, and his contact balance is unusually good for a player whose lower body was still underdeveloped. He is a two-sport athlete (basketball rebounder and rim protector at Langston Hughes), which shows up as body control and high-pointing ability. What the tape and evaluations do not show is consistent vertical burst; he is long and coordinated more than he is explosive, so the frame projects to a Y/H hybrid rather than a pure seam-stretcher.

Play Style

Tiller plays like a big-bodied possession target who wins with reach, timing, and physicality after the catch. He attacks the seam with good agility for his limb length, uses his frame to box out defenders on back-shoulder and red-zone throws, and turns routine catches into extra yards by running through arm tackles. He is most effective on play-action leak routes and in the middle of the field where his catch radius overwhelms linebackers. As a blocker he is willing and often finishes, but his execution is inconsistent because his technique lags his effort. His overall tape reads as an athlete still learning the position rather than a finished tight end, which is why grades ranged from 90 to 92 across the cycle and why his ranking slipped from top-100 status in early 2025 to just outside the top 150 by signing day.

Strengths

• Catch radius and hands: freaky-long arms plus large, strong hands produced what 247Sports called an 'unreal catch radius at the prep level,' letting him win contested throws when he is not actually open. His 57-yard touchdown vs. Lee County as a senior is the representative play.
• Contact balance and run-after-catch: defenders bounce off him after the catch despite his weight; 19 career touchdowns on 70 catches (a 27% TD rate) reflects how often he finishes plays and how heavily Langston Hughes used him in the red zone.
• Blocking temperament: technique is a work in progress, but he shows a willingness to finish blocks and the strength to back it up, which is the trait that keeps him on the field in Florida State's tight-end-heavy sets.
• Alignment versatility: comfortable in-line, at H-back, in the slot, or split wide, and Florida State recruited him explicitly as a 'malleable chess piece' in the Randy Pittman Jr. mold.

Areas to Improve

• Vertical explosiveness: evaluators flagged that he lacks the consistent vertical ability desired at the position; he separates with length rather than speed, which will matter more against Power Four safeties.
• Processing and proactivity: film shows him reacting rather than anticipating, both as a blocker (angles, hand placement) and as a route runner, so he needs reps to play faster.
• Volume and refinement: his prep production was modest for his ranking (25/352/7 as a sophomore, 25/344/3 as a junior, roughly 20/358/9 as a senior), and he never carried a large route tree, so route depth and stem work are underdeveloped.
• Functional strength at the point of attack: the weight gain is a positive, but he must convert it to base and anchor before he can be trusted in-line against ACC edge players.

College Projection

Year 1 (2026): depth. Florida State's tight end room is crowded with senior transfer Desirrio Riles as the starter, former No. 1 TE recruit Landen Thomas, and redshirt freshman Chase Loftin, so the staff can afford to bring Tiller along slowly. Coverage out of spring and fall camp called him possibly the most natural pass-catcher in the room and noted his athleticism gives him a chance for early snaps, so a four-game redshirt with special-teams and red-zone package work is the realistic outcome; full-time contribution in Year 1 would be a surprise. Year 2-3: rotational flex tight end with expanding targets as Riles graduates and if he holds 235-245 pounds. Year 3-4: starting-caliber receiving tight end if the blocking and processing come along. He is a patience investment rather than a plug-and-play signee.

NFL Outlook

Legitimate draft-track traits: NFL-plus hands and wingspan at 6-5 with a frame that has already added 25-plus pounds since commitment. Contact balance and catch radius are the two traits that translate most directly. The questions are the same ones the league asks of every flex tight end: does he test well enough vertically, and can he block well enough to stay on the field on early downs? If he develops into a 245-pound Y who blocks adequately, he profiles as a Day 2 or Day 3 pick after his third or fourth year; if he stays a move-TE with limited blocking, he is a late-round or priority free agent type whose size gets him a camp. Realistic range: Rounds 3-6 in the 2029 or 2030 draft, dependent on production that has not yet happened at any level.

Best Fit

A pro-style or multiple-tight-end offense that uses 12 and 13 personnel and moves its tight ends around the formation, which is exactly what Florida State runs under Mike Norvell. He needs a program with a strong strength staff and a veteran ahead of him for at least a year, and a play-caller who will manufacture red-zone and play-action seam touches while his blocking catches up. He would be miscast in a spread offense that asks tight ends to run a full receiver route tree with speed, and in a heavy-run scheme that wants an in-line blocker on day one.
