Costello was one of the most fundamentally sound players at the event. His 4.5 5-10-5 time was solid, but what really stood out was how clean his performance was throughout the day. He made little to no mistakes and consistently executed drills the right way. His attention to detail and willingness to listen translated directly into strong reps.

He showed a high football IQ and an understanding of positioning, leverage, and technique. Coaches should be excited about his coachability and foundation, as he already plays with discipline and control. While flashier athletes may draw attention, Costello is the type of linebacker who wins trust quickly and develops into a reliable, productive defender in a college system.
