Some of Smart's hype is a carry over from his success prior to college. He is a very good player, but you have to admit he started out higher than Buddy.
It is similar to college football. It is easier for the team that starts out No. 10 in the nation to when the national title than the team that starts out unranked, even though the two teams might be similar.
That said, Smart is a better player, or at least, a more polished player. Buddy is very good, however. On a scale from one to ten, if Smart is an 8, Buddy is a 7.
