Nubin's play style is characterized by his physicality and ability to make plays in run defense. He shows strong instincts and is a confident downhill defender. However, his coverage abilities are less consistent, often struggling with maintaining momentum and effective tackling techniques. His ideal scheme fit would be in roles that leverage his run-stopping abilities and straight-line speed, likely as a zone slot/nickel safety or in two-high safety alignments with opportunities to move into the box.
