No comparing saying ones better then the other or anything like that. In the end we need someone who can shoot the deep ball and we will get that from Copeland over Morrow. Like you stated Morrow was more physical down low and Copeland can be physical enough but has and the outside game as well which does give defenses fits, even more when its a number 4 guy that can shoot outside shots. Giving Credit where its do, Copeland appears to have the rebounding and shot blocking ability too. Copepland appears to have the end in leaping ability, Morrow is more physical but Copeland is more athletic.
The one poster above is dead on, to bad we can't have both of them and not one or the other. But as long as Copeland comes back to his old self and keeps progressing we will have a very athletic 4 man that can shoot the long shots, along with the inside game.
