Looks like the English FA is channelling the juggernaut political idea factory inside John McCain's mind, and has angered the Barclaycard Premierhood with talk of a salary cap. A salary cap would, of course, set the Premiership on the road towards competitiveness, and thus ruin for the over-extended Big Four: they all need to make the Champions League group stages every year and tap those unfairly allocated television revenues, less the whole Ponzi scheme collapse. (And listen, Arsenal can't beat Hull City as it is—what would happen if they had to mind the balance sheet?)
Global financial worries aside, I think it would make more (or at least as much) sense to: A) cap squad sizes; and B) cap the amount a club can spend in a given transfer window. Liverpool has something like 50 guys listed on its current first-squad roster, which is absurd. Why not limit clubs to, say, 25 players plus however many senior players they can bring up through their own developmental teams? Under that formula, if a club really wanted 60 players, they would have to home-grow most of them rather than stockpiling transfer-market players who they'll never use: no more buying Swiss internationals for the occasional League Cup match. Meanwhile, if clubs faced a limit of, say, 25 million pounds total in a single window, it would force the big boys to pick and choose and curb inflation of transfer prices overall.
Now, anything else?
