Stats aren't publicly available as far as I know. The difficulty is the poor definition of giveaway and the interpretation of what it means. I would classify a missed shot as technically a giveaway. Deployment matters. William Nylander starts in the defensive zone only 7% of the time and missed the net 17 times more than Marner. Seems more contextual, no?
In any event, here are the top 20 in the league for giveaways. I've included takeaways. If the intent is to prove Nylander is just a better player, I would like to see his advocates argue the same thing for people on this list.
BTW, note the anomalous takeaway king of this bunch
