I think that if we draft Moore and he turns into Larkin, you're ecstatic with that result and we can totally win cups with them as our top two centers (especially if Kasper is then some sort of elite 3C or a good top 6 winger).
However I would be disappointed with Moore at 9. I love a guy that can skate and thus had Moore as an option at 9 a few months ago, but I've moved him down the more I've watched him. I'd be cool with him at 17, but he's not going to be my first choice there either. I don't feel like Moore has the overall game for Larkin to be a likely outcome. Besides his speed, I have his shot as his only + attribute. I think you're getting a guy that will skate himself into trouble and has neither the hands, smarts or passing to open up space for using his shot. So he'll end up blowing by everyone to the outside and funneling an off-angle shot on goal most of the time. I think you're probably getting a solid 3C that can skate and score the odd goal, but not consistently impact the game offensively.
To be fair, I would have said a lot of these same things about Larkin whom I viewed very similarly but with better size, smarts and hands but a worse shot. I'm not sure that I really learned my lesson from Larkin. I question how predictable him becoming this good was. It sort of seems to me that he met or exceeded expectations in every way, and I'm not sure I'd bet on that happening again. Maybe I still underrate the impact that elite skating has. Maybe I still don't give "you had reduced opportunity because there were elite players in front of you in the lineup" enough credence for explaining good but not great numbers. Maybe I prioritize a guy being able to make a creative pass too highly. Maybe I care too much about a guy showing an ability to anticipate the play and tilt the ice in his team's favor.
