Goalies tend to be goalies because they are not good outfielders. They have an area where the rules of the game are different for them and only apply to them.... so stay there.
What Marshall was doing 1/3 up the pitch when Schick got the balll in his own half is anybody's guess I mean, come on!
It was a wonderful strike, no doubt about that, but if Marshall had been in his area, though well forward in it, he could have got back - he nearly did - a needless give-away goal.
