Teams will always tank. They still do, even with the lottery. The only thing the lottery accomplishes is teams are tanking for MORE years, trying to get that once in a decade pick. I would say that if the worst team, got the first pick, there would be less tanking going on, honestly. And as much as tanking gets cheesy, can you blame the teams that do it? They can't compete with the Heat and sign 3 all-stars. Tanking and hoping to grab a superstar is all they can do. Even so, Hornets need excitement NOW so I'm not OK with them tanking, not when there are some good big men free agents out there that would help us a lot. Besides we have to spend to reach the min. salary, so why not? We need to make money now, and put people in the seats.
You are right that the worst team should have a higher %, like way high, but by then, why even have it?
I've always said the lottery is rigged, if it wasn't, they'd throw it on TV and make quite a bit of money out of an hour or two program where you could watch it live.
