Of course they are all percentage balls, but the difference is that you increase the success % based upon the type of ball you put in and where your service is aimed at. If nobody is making a run and not in goal scoring position, holding up the ball is one of the few logical things you can do without just handing the ball over. If there are players in the box but it is far too crowded for players to make a run, they need to put the ball into the area that has the greatest success.
More often than not, Lennon had a tendency to break a run, get down to the end line, and force a cross that just seemed to be about getting a ball into the air than anyone in particular. Usually because he was fast but didn't have 100% control at the time. Quite often, these balls were floated in and collected by the GK, went over the end line, or floated way over to the other side of the box where nobody was in an attacking position.
I get that and I completely agree with your point and

that the biggest problem was the inconsistency of the final ball.
My issue is with
Burko
claiming that the winger bears no other responsibility for accuracy other than getting the ball to or right around the penalty spot. Maybe the ideal spot isn't the penalty spot. Maybe it needs to be flung in low and fast, or needs to be a floating cross to the far post. There's no doubt that attacking players need to time their runs and work themselves into position to go after crosses, but the winger's responsibility isn't only to get the ball at the penalty spot and forget about everything else.
