Having negative categories is definitely one good way to counter the strategy. We've used Total Bases Allowed the last few years for the same purpose. It devalues churning, not starting pitching. Of course while you're managing the "too many starters" problem, you also want to bear in mind the "all relievers" problem. Do things to keep your managers from rolling too many starters out there, but then make sure you also set a solid Minimums Inning value, to make sure they have to start a few guys. Ideally you've got a nice balancing act, where managers have to wrack their brains over how many guys to roll out, and there's no obvious advantage to extremes in either direction. Managing your pitching staff should be the most challenging aspect of H2H -- don't make your managers' decisions easy.
