Who has the most natural raw talent? Probably Lopez. Quick, explosive, powerful, broad shoulders, twitchy.
Ryan has lightning quick hands and good power, good size even up to 147. If he can become more defensive aware then skies the limit. His only questionable trait is his heart.
I'd say Haney at present, the rest seem to be moving to 140 aside from Loma. The key word here is potential, and the name Shakur is loaded with,,, potential .
