As far as I can tell, the stats this season show that the shots faced by Collins have generally been fairly easy (which is not to criticise him for saving them).
Wilson was similarly fortunate last season, partly explaining why his stats were so good.
Struggling to think of any properly brilliant stops by either of them this season, and neither is commanding on crosses.
Both just OK for this league IMO, but hardly outstanding. If I had to choose it would be Collins, but boy I wish he wouldn't spend two minutes every time to do something with the ball.
