The only negative I noticed with Spence is he gets caught on the wrong side in his own zone, he sometimes drifts too far to the outside. A minor, positional thing that can be taught. He's been damn impressive. Same with Grans, I wasn't expecting him to look so polished.
It's very weird to see Kings prospects games where they are obviously more skilled, creative, and prepared than the other teams are. I think we are finally seeing the change in draft philosophy over the last few years and reaping the rewards for being so shitty lately.
