for me a lot of defensive line play is instinctual and sometimes it looks like he is overthinking. Phillips is a smart player but if you watch a vet like Lotulelei in the middle for example, you'll see him in 1tech getting pieces of guards in zone to buy an extra half step for the LBs, keeping his footwork balanced when he needs to have a different angle...I rarely see that ability to adapt out of Phillips. He knows his responsibilities but doesn't have any counters when the situation calls for it
