Bruce Feldman placed Jackson Cantwell No. 4 on his annual college football Freaks List, while Miami’s testing showed the 6-foot-8, 330-pound lineman producing more peak power than Francis Mauigoa. Patrick Previty of Canes Warning detailed the numbers after the list appeared Monday.
Cantwell reached 9,461 watts, compared with 9,273 for Mauigoa, and recorded a top speed of 17.3 mph. Mauigoa reached 17.6. A freshman that large getting that close to an NFL first-round tackle in two different testing areas owns unusual raw material.
Bruce Feldman of The Athletic also connected Cantwell’s profile to his elite high school throwing background. Cantwell grew up around Olympic-level shot and discus knowledge and became an elite thrower himself. The power required to generate force from the ground through the hips and hands has an obvious offensive line translation.
Guard can simplify the first assignment without making the job easy. Cantwell would operate in tighter space, where his first two steps and ability to move a defensive tackle matter more often than recovering across an entire edge. His power can turn a correct angle into immediate displacement on combination blocks and short-yardage runs.
The position also creates new problems. A 6-foot-8 guard must keep his pads low enough to avoid giving a shorter tackle leverage under his chest. Interior pass protection arrives faster than a tackle set, and twists require rapid communication with the center and tackle. Testing numbers cannot make those details automatic.
Miami is evaluating Cantwell at guard because the offensive line is searching for its best five, Jordan McPherson of the Miami Herald reported. The context should keep the experiment in proportion. The Hurricanes are not declaring that their future left tackle belongs inside forever.
Alex Mirabal can use the work to accelerate Cantwell’s education even if he does not start there. Guard reps force the freshman to recognize fronts from a different perspective, feel help from both sides and play with efficient hands in crowded space. Those lessons can make him a smarter tackle later.
Miami also has to protect the long-term asset. Constantly moving Cantwell between positions could slow his footwork and prevent him from becoming comfortable anywhere. The staff should give him a defined block of guard work, grade it honestly and return him to tackle development if the best-five argument does not become clear.
The power number makes early playing time plausible, not mandatory. Miami has older linemen who understand the offense and have handled college movement. Cantwell has to beat them through consistent technique, not recruiting status or one exceptional test.
The best outcome is a useful choice. If Cantwell wins a guard job, Miami gains rare movement ability inside while preserving future tackle options. If he does not, the experiment still exposes the details he must improve. His 9,461 watts make the test believable. His daily film will decide whether it becomes Miami’s answer.
