Costly misses I can remember are the late headers he missed against Sheffield Utd and Leicester.
His confidence infront of goal has completely deteriorated but we must remember his goals have also got us some valuable points (particularly at the end of the season).A couple more goals and hopefully he'll get back to that level.
Logically if you can pin down points cost by the chances he misses, then he can't surely of cost us point v Millwall as he wouldn't have been there to score the first goal
As I said on the other identical thread .... stupid question.
His defensive play has probably prevented goals against us ... who is to say how many .... would someone playing in his place have scored the goals he has scored?
So the answer to your stupid question is .... NONE.
