I think you are reading too much into this whole "OMG we win more without Parker" thing which may be statistically correct but when you have to rely on stats which can be interpreted a whole number of ways, I think you're clutching at staws.
OMG we win more with Krul in goal than Shay... statistically anyway.
Over 2/3 games you might well be correct but over a season and a half a certain pattern will have time to emerge surely?
