I don't know how accurate this is (spy???) and it's off of nbadarft.net so take it fwiw but here's how it opens in describing Johnson.
"Strengths: The first two things that jump out are his incredible football player like body and his competitiveness ... He's a standout with his on ball defense where he is able to use his huge chest to muscle any offensive threat ... But compared to Ron Artest, he looks like a much better defender off the ball, using his large wingspan to deflect passes and his big hands to snatch the ball away from opposing players ... Defensively, he's absolutely a beast, who could immediate play in the NBA creating problems for many NBA wings ... Perhaps another of his best characteristics, really rare in a 18 year old is how he plays to his strengths, never takes a bad shots, never tries to show off, instead takes what the game gives him."
Sign me up. This is what this team needs. I think it would make Gobert even more passionate and Favors some as well.
