Great to see him out there doing that. Chris Kaman is a character but I don't think he's blowing smoke when he says that the guy should have been a first round pick. I've been watching a lot of footage on Cliff and I'm surprised he went undrafted.
I bet a lot of people might not know that Cliff played highschool ball vs Jahlil Okafor in Chicago. A place where a lot of big names seem to come out of. Cliff wasn't just some dude balling for some HS though, he was a big name athelete. The chicago tribune voted him player of the month his senior year in December. However he did not win the Mr. Basketball award mentioned in the article - That award went to Okafor. Alexander did however win the Sun Times player of the year award for 2014. Interesting quote from Sun Times writer Michael O'Brien on Alexander, I definitely recommend you read the entire article.
For the next 20 years, area big men likely will be compared to Alexander and Okafor — Alexander as the gold standard for speed, power and athleticism; Okafor for technique, poise and polish.
