You guys need to understand that Ricky has, in fact, failed his 4th drug test. Whether it was caused by actually taking the drug, or a yoga supplement or diuretic or whatever, by definition, he tested positive for a banned substance. Everyone seems to think he'll win his appeal so easily, but the burden of proof is on him to prove he didn't in fact take the substance he tested positive for. Proving that another substance can cause an erroneous positive result is fine, but it doesn't prove to the committee that the guy who already failed 3 tests, is innocent. I think the odds are stacked against him. The only things working in his favor are his talent and value to the league (let's face it a mediocre talent gets less consideration), and hopefully he tested positive for something other than pot. His very public healthy lifestyle is really only a few months away from admitted heavy pot use.
That's why I think Nick is smartly looking at Michael Bennett and probably other options as well.
