2015 Review: What Ourlads' NFL Scouting Services said about DAVID MAYO: Texas State. Was a tackling machine at Texas State and is an instinctive downhill player. He was named the Sun Belts’ Defensive Player of the Year in 2014 after collecting 154 tackles, the second highest total in the country. Pro day numbers: 6010, 235, 4.78/40, 24/BP, 34.5/VJ, 9-5/BJ, 4.35/SS, and 7.17/3 cone. Mayo will have to make his mark on special teams to roster for the linebacker-rich Panthers.
