Rugby Union legal battle brewing as players set to fight for right to 'data'

To my non-lawyer sensibilities it seems that while they might have claims on data protection and FOI terms, I don't think they can claim copyright, or ownership based on the claim that they "create" the data.
And one other thing:
"If a club believes a player to be prone to say concussion, they may well not wish to sign him."
This sounds fair enough to me!
Furthermore it would be negligent in my mind to put them in a job where they might suffer more concussions.
Frankly, it seems like a waste of time: commercial third party analytics have been around for years in other sports where they represent much better performance indicators and lead to much bigger salary differentials, and even in the unlikely event they win they'll succeed only in having standard contracts rewritten and players that refuse to share their data being regarded as a bit suspect.
The UK has ended up with oddities before, like association football scores technically being the intellectual property of licensing troll FootballDataCo, which still picks up revenue despite its copyright claims being ruled unenforceable by European courts. But it's unlikely to end up with oddities detrimental to the clubs and league.
