Not your main point, but just touching on this because I've seen other people say it in this thread but, why do people assume 40 goals for him? He hasn't shown the ability to be close to that, both in terms of actual production AND inclination to shoot enough to reach those totals.
The last two seasons he's registered 152 and 140 shots on net, respectively. No chance in hell he's near 40 goals if he's only generating that few shots. Not unless he has a fluke year where he shoots like over 25%.
Knies has never struck me as a pure goal scorer. He just seems like the type who could be in the 30 goal range in a good year, but not some sort of elite goal scorer who can hit 40. At least not without almost doubling the amount of shots he takes.
