His only "good" games have came against well below average talented teams. I challenge anyone to show me one good game he's had against a tournament level team.
When he has to play against athletic, long, talented teams he becomes a 100% liability.
I hit "reply" the second I read this, but lets look at the facts on that.
Tournament Locks
Wichita State - 13 points, 6 rebounds, 4 assists, 2 steals
Creighton - 23 points, 6 rebounds, 1 assist, 1 steal
Kansas - 4 points, 3 rebounds, 3 assists
Baylor - 8 points, 3 rebounds, 4 assists
Texas Tech - 16 points, 3 rebounds, 3 assists
Kansas - 12 points, 5 rebounds, 4 assists
WVU - 6 points, 2 rebounds
Baylor - 2 points, 5 rebounds, 3 assists
Mississippi State - 9 points, 5 rebounds, 3 assists
The allegation doesn't seem to hold water. He has averaged 9.7ppg and 4.1 rebounds against these 9 NCAA Tournament locks, which is solid production. There are some catches to that though...
Against Creighton he was 4-16 from the field
Against Baylor in Waco he was 3-17 from the field
Against Kansas he was 1-9 from the field
Agaisnt Mississippi State he was 3-14 from the field
Etc...
So the production is decent, but the devil is in the details. These are the numbers though. They are what they are. Feel free to interpret them however you like.
