These all-star games are not a very good indicator for either of the future Buckeyes playing in them. Buford is an unselfish player known for his mid-range game and pretty tough in your face defense, and Mullens can only show when his teammates make an effort to get him involved.
BJ ran the floor very well tonight but was always just a little late and someone else got the bucket, he did show some good footwork and excellent hands. His defense looked pretty good, but his opponent seemed to always be taking him away from the bucket, so he could not help weakside, that won't happen as much in a structured defensive scheme, man or zone, and he'll be able to show off his athleticism on the defensive as well as the offensive end of the floor.
The important thing is that both guys came out of the all-star circuit healthy.
