Romero is a disciplined, assignment-sound edge defender with a strong understanding of defensive structure. On film, he consistently sets the edge with proper leverage, uses his length to maintain containment, and reads his keys to stay home without overcommitting. His technique-focused approach allows him to impact the run effectively while remaining versatile enough to drop into coverage when needed. He shows comfort playing in space and awareness of developing routes, making him a reliable, multi-faceted defensive contributor.

He projects as a 3–4 outside linebacker or edge rusher in schemes that value positional discipline, length, and versatility. Romero’s skill set allows him to set the edge against the run, rush the passer in controlled situations, or drop into coverage as part of a hybrid system. His football IQ and ability to operate within a structured defense give him long-term value, particularly in schemes that reward technique, leverage, and smart play over pure speed or freelancing. College programs can deploy him in multiple roles without changing his effectiveness.
