Not really. When you pack the defence, the number of on-target shots that are :
- deflected away from goal is going to be high
- get thru the gaps or are deflected in such a way that the GK is in trouble is
going to be low(er)
Saw the above in the Chelsky 2012 CL SF away leg against Barca.
You are talking about one game. The stat is for the whole season.
Talking of Chelsea, it is what Lampard did so well. Eventually one of his off target shots got a deflection and went in.
Simple ball over the top and it's in.
