A person in a wheelchair would have stopped this shot.
But a goalkeeper can't always know where the shooter will put his shot, so will often guess and go to one side in case it's a hard hit shot. On other occasions he'll wait.
In open play goalkeepers will normally wait and use their anticipation and reactions. Vitally, defenders will be of help, often shielding part of the goal, often putting the shooter off balance, or forced into a less ideal position to shoot from.
This season our defensive problems has meant shooters often have had unchallenged shooting opportunities, got into great positions to shoot from, and been able to whack it very hard, and/or pick a spot out of Cooper's range. On some other occasions, the finishes haven't been great, but still beat him as they haven't gone where he expected (like the Panenka) and therefore failed to readjust his body.
Looking at the goals we have conceded this season, do you think the XGoT stat takes the above into account?
