Information works like this: garbage in, garbage out. We can't help the fools who believe there's any meaning whatsoever in those numbers. Those numbers don't warrant any serious discussion.
You couldn't be more right. Why do people bother talking about the tracked giveaways, takeaways, or hits for that matter? These stats are total junk. Watch a game where a particular player has at least a dozen giveaways, then go look at the official numbers. It'll usually be listed between 0 and 2. Look at the giveaway leaders at the end of a season, who the hell actually believes that the person with the most giveaways in the entire league has about one per game? ONE PER GAME.
If this could tell you anything it's what players get the most icetime and carry the puck the most, comparatively, because the numbers relative to each other might be sort of right. Or not at all, depending on how they're tallied in different arenas. If you look at the numbers from 2 seasons ago Kovalchuk led the league with over 20% more giveaways than the second place, Getzlaf, who was himself about 20% higher than 10th place. It really doesn't make any sense.
