But tanking worked for us, only 5 years ago!! Of course it's not fool-proof. It's very risky. But it's far and away the best option to get your team back into prominence, as opposed to doing minor tweaks and remaining in perpetual mediocrity.
Remember back to the Walker-Pierce Celtic era. We made some trades here and there, and got a tiny bit better or a tiny bit worse from year to year. But it wasn't until Danny finally came in and flushed away Ricky Davis, Payton, Cassell, etc., and kept Pierce out for 30+ games - with a sore foot lol - that we finally got the lottery pick we needed to get Ray Allen. And that of course is what led to Kevin Garnett choosing to come here.
Without that tank season (which could have landed us Durant or shudder Oden had it gone differently) none of that would have happened.
