The real concerning thing about the trade that Hollins seem to have got right is that advanced stats were completely wrong about Rudy Gay's value. His production was a victim of the system he was in. Hollins' offensive philosophy actually diminished Rudy's productivity.
So, he had a terrible PER this year, but it was largely not his fault. As the True Hoop article from a couple weeks ago pointed out, Rudy was just taking the shots that the offensive system produced, and a LARGE portion of those shots were contested mid- to long-range jumpers in the last seven seconds of the shot clock. Those shots aren't going anywhere because you've traded Rudy Gay. All that's going to happen is that someone else is going to take them; probably Tayshaun Prince, Tony Allen, and Jerryd Bayless.
The problem was always Lionel Hollins. But, since he led to a better record every season he's been here, people would say it was stupid to fire him. The fact is, the assistant coach is the reason behind our elite defense, not Hollins. Its kinda like Thibs when he was behind Doc Rivers. So, it just seems like Memphis is moving all of their talent away while keeping the problem on the team.
