Good question.
I had him at 3 for a good chunk of the year, but have since dropped him a few slots. Still in my top 6, but there are concerns.
The talent is there. From a pure talent standpoint, I think he's the second among wings and third among forwards overall. If you think Kakko is a center, he slides into the top spot for talent on the wings.
But, the sum this year has not quite been equal to the parts. It hasn't been bad, but it hasn't made him the clear-cut third best prospect in this draft --- and you can argue Podkolzin should be firmly in that spot.
But when he's on, he's arguably one of the most electric players in this draft. The question is how much do you want to gamble on that, with some of the other talent that will be available?
Additionally, there are some mixed signals about his desire to come over to the NHL, at least in the more immediate future.
Regarding the latter, that's might be more of a concern if you're Colorado, or New Jersey, Edmonton, or even Anaheim. But I don't know if it's as big of a concern if you're Detroit, L.A., or New York.
Podkolzin's offensive ceiling might be the third best in the draft, the question is whether teams feel there are other options who have slightly higher probabilities (at the cost of some ceiling).
I don't know if I see him falling out of the top 10, but maybe a mini-fall like Zadina?
