I don't know, maybe this is a contrarian take, but I probably have Pieniniemi>Pickering as of right now. I feel like everyone is just anchoring on Pickering's 1st round draft capital as I haven't really noticed much progression to his game besides bulking up a bit.
PPG as a dman in his first season of NA hockey is nothing to scoff at. 10 pts in 11 games in the playoffs and was one of the best players for Team Finland at the WJC (1st pairing and PP1). Breakout season for sure. I don't know how high his ceiling is, but there's a bit more offensive upside there than we probably anticipated.
