Warren and Bowers are completely different archetypes.
Bowers is your elusive fluid athlete. Who wins by route running and natural feel of the game. Sure his speed helps but it's his fluidity that makes him special.
Warren is stiffer but significantly larger. He wins off his ridiculous size advantage. He doesn't need to create the separation Bowers does because he can just physically dominate his defender by virtue of being 3+ inches taller and 40lbs heavier.
