Tennessee vs. Pavel Datsyuk et al

The NHLPA's general counsel, Steve "Don's Brother" Fehr, said Tennessee could face lawsuits if the jock tax isn't repealed:

"There are a lot of NBA and NHL players who could pursue claims to get their money back either through refund request or litigation," Fehr said. "We've looked at it and we think it's a viable case."

Based on what? We're not sure. While Fehr notes that the recently approved CBA requires the league and union to work together to repeal the tax, he doesn't mention that the CBA requires the league to pay the players' portion in the meantime.
