Difference is Karlsson, Donskoi and Sorensen were really good players in their leagues. Rod has made very little impact. Big year for him.
I'll be very surprised if Rod ever makes the NHL.
Rod played this entire last season as a 19 year old. He just turned 20 on June 7th. None of those guys were doing much at the same age, except maybe Donskoi, and he's amazing. Rod's very young for his draft year, and I think he deserves a little more time before we declare his fate.
