Things like catching the ball in the air in his own box to help the team relieve the pressure, sweeping for the long balls to make us play higher line, not hoofing it with every ball to keep us in possession. Maybe it's too much to ask, for that reason he also doesn't make that many errors but that's only because he's not contesting for the balls.
All of the small things will add up though and even excellent shotstopping can't even out his overall contribution. And to be frank, he's got a top save here and there but week in week out I see amazing saves from arguably worse keepers too and today he let in two easy goals from tight angles, on anotherday big active keepers could stopthat while keep us in the game much better than Dave. It's time to make that call ETH, hopefully he's not blind like with some other palyers..
