Agreed 100%. Both Mayo and Guyton possess tremendous physical skills. They key question is can they deliver on what BB appreciates the most out of a player in this defense- solid fundementals & tecnique, playmaking, toughness, and based on the situation, making the right reads & decisions based on the situation. Mayo is obviously well on his way. I'm very high on Guyton's potential and if he can provide something close to what Bru gave the D in his prime, I'd be pretty pleased with that!
