Been beating this drum for years, sent the odd email off to HQ but all I ever get is a polite reply.
The salary cap was introduced for a number of reasons, but the main reason was to even out the comp and spread the playing talent around. In a way it has done the opposite, some teams have just their cap to spend and the odd TPA, where other clubs, have their cap, their full allotment of TPA's and are in the position to direct endorsement towards their marquee players that don't come under the TPA umbrella.
The argument will always be, if you can't beat them join them, but that is not always possible and some teams for a number of reasons have a big advantage over others. In a perfect world it would be nice to think all 16 teams have a real chance of making the 8 and than anything is possible, but that is not the case under the present system. We will end up like the EPL soon where every year the comp is dominated by a handful of clubs.
Sorry for the rant..but all I want is a level playing field or something very close to it
