SVG is a good coach, and a pretty decent evaluator of NBA talent. He's made some pretty good moves as GM.
The problems in Detroit can mostly be traced to Reggie Jackson sucking this year. I thought at first it was just due to injury and the time it would take to recover and get back in game shape, but it looks like he just flat out sucks.
Also, while SVG is a good coach, he has a very grating personality. Teams only listen to him for so long before they get tired of him and tune him out. I didn't think it would happen this fast in Detroit, but it looks to be the case.
Either way, I'm kind of reveling in them falling flat on their faces.
