I think you miss the point. For example ...If they are both 50% shareholders in the development company. Player X invests £500k Director Y invests £500k. They buy and development a site...sell the units and make say £500k profit...they both walk away with £250k each. No payment to the player at all! The issue is that Player X has no experience or sufficient capital to do the thing himself and the additional £250k in his pocket would not have happened. There is no payment to player...just business experience and a share of the financial capital.
I guess it depends on who has actually invested what in each company, if player X invests £200k, Director Y invests £800k, They buy and develop a site...sell the units and make say £500k profit...they both walk away with £250k each. Not sure in that instance it can be classified as a joint investment with equal shares......
Also as this is allegedly about property and who owns what, it's also about what any potential rents are being applied to player X in that property that may or may not quite be at market value, (another point that is included in the salary cap regulations).
Also, the point I mentioned from the regulations is about something that is only available to players of the club, I'd bet Director Y wouldn't do a joint investment with a player not at Sarries.
So, no I don't really think I did miss the point.
However I still expect them to get off as it would put into question a number of championship wins and not sure the RFU, Prem Rugby, EPCR & CVC want that can or worms opened.
