Think assists are a good stat as well, the rest, as you say, is so open to interpretation.
Key passes I do think are important too - although defining them I agree is difficult. Just imagine Messi playing at Burnley ( I know...).....killer passes on a plate all game, only for Chris Woods to spoon them over the bar. Messi's assist tally drops, but his overall contribution is still right up there.
