Other boards/clubs do this, but it's never been mentioned on here. Do the Dragons do this and would it be something this board could do?

over recent years all the Catalan players have been sponsored indiviually by local companies,if that's what you mean ? When a player scores the sponsor is usually mentioned when the name of the scorer is announced.

Not sure there are the numbers on here to do it. Correct me if I'm wrong.

if you look on the Catalans site and look at the 1st team squad - click on each player ie J-P Baile and at the bottom you will see the sponsor ie 'jouer parrainé par Joe Bloggs'
