I think it shows more that they where both physically very mature for 17 year olds, thus they dominated a bunch of lanky Euros.
Agreed, but I still think Koufus had enough talent to be a productive starter for us if he wanted it bad enough. Kanter obviously worked really hard to come into the combine and his workouts in great shape and if that is the kind of work ethic he will show throughout his career, he should develop into a very good player.
