Cushing Claims He Passed a Polygraph
Adam Schefter of ESPN wrote on Twitter that Cushing took and passed a lie-detector test in an attempt to demonstrate that he hadn't taken performance-enhancing drugs.
It's not clear, however, who administered the lie-detector test, and it's also not clear whether this was something the NFL asked for or something Cushing did voluntarily. But it is clear that this is something Cushing would like to get out there as evidence that he didn't actually use performance-enhancing drugs, even though the NFL says he did.
Ultimately, however, it doesn't matter if Cushing passed a polygraph test. The test that matters is the urine test that he submitted to, and that test says he's a cheater under the league's policy on anabolic steroids and related substances. Cushing can make all the denials he wants, and all the claims about passing lie detector tests that he wants, but the bottom line is the under the league's own rules (which the players and their union agreed to), lie detector tests don't matter.
In the NFL, only urine tests matter, and the urine test says Cushing broke the rules.
