Yeah, that's the well known drawback, and for us I consider it to be a major one. If he is a major star level offensive player, you probably have to take him anyway, but there is no hope, none, defensively for a Hawes/JT/Griffin trio up front. Griffin's hustle is offensive in nature, he is not long, has no shotblocking instincts, and I think has a more lively off the floor body than true brute lower body strength body. And contrary to what people sometimes like to claim, players rarely dramatically change their stripes by the time they hit the NBA. If he's 20-10, then you just have to accept it and try to figure out some way to load the team up with defending rolleplayers to make up for your best players being crappy defenders. But if he's anything less...something has to give.
While I agree that Griffin has show NOTHING defensively yet at the college level, I really dont think the coach wants him to because of all the energy he is forced to use on the other end. I would like to see him be a LOT more aggressive, but if he gets into foul trouble the team is royally screwed.
He doesnt have the tools to be a dominant defensive player .. they just arent there. I do think he can be an at least average defender though, he has the strength to keep a lot of the thinner PF's off the block .. you never know.
Wishful thinking perhaps, But this team has a 'no defense' culture. Its going to take a lot to fix that ... All of these players can play better defense than they are right now ..
