Pretty impossible to say, to be honest, though I'd suspect it was decided last season, since it was pretty much known beforehand and no doubt was part of the negotiations in getting the other clubs 'on-side' with the deal.
You are repeating the old canard about getting "extra" funding last season; they did not, they just got some Sky payments early, that's not quite the same as getting more than they were due. It's very true that a number of clubs gave donations to the Bulls in the form of free tickets or giving the club all the entry money paid by Bradford fans, and all of us, fans, players and officials are very grateful - it helped to save the club and, along with other efforts, is directly responsible for the club being in SL this coming season. Are you suggesting they are taking it back? quid pro quo?
I've said before that I don't think there is any point in 'fining' the new owners - they are blameless - but, if we are to start at a disadvantage then so be it, but why has half our Sky money gone to the other clubs, putting us at a bigger disadvantage?, why not put the cash into funding youth development, promoting the international game, maybe as part of an RL fund to help badly injured players at all levels - I'm sorry, but I can find a number far more worthy causes than jusxt doling out the money to the other SL clubs.
Leeds gave the Bulls administrator a considerable sum from their home game against Bulls. That was to pay players, and Is a gesture I will not forget in a hurry. I think we gained a better idea through all this which clubs were our friends...and which we're not.
Warrington and Hudds gave over £7k and over £3k respectively to the Bullbuilder Hardship fund ( not the club or the administrator, and deliberately so) from sales of away tickets. I was not involved with the Hudds arrangement, but dealt with the Warrington one and found them to be very sympathetic and helpful. The hardship fund made donations to staff working without pay and their families, and those donations made a significant contribution to there still being a club now.
Not sure what other direct contributions there were from other clubs.
I really wish I could see the logic of punishing a totally new company, seriously hamstringing it and raising the bar perilously high for it to have chance of succeeding, for the sins of a previous company and it's warring shareholders. But I admit I cannot.
