Rhattigan waited a long time for his chance and made the most of it in 2020. Possessing a muscular frame with big hands, he plays with good strength and an attacking brand of football. He is quick to diagnose play flow, which helps him play faster than his timed speed. He's a team-oriented defender willing to plug run fits and play inside the defensive concept. He's always ready to get to work as a tackler operating from a durable, balanced platform as a wrap-up finisher. He has occasional coverage missteps, but is typically aware and looking to make a play when dropping into zone coverage. He's tough and reliable with special teams value, but backup duty is his ceiling.
