Admittedly no, I haven't seen him play much, but a 70 game player with 16 points doesn't scream Top 4 puck moving PP quarterback. He's in the age group, but we need that final D man to lead the PP man, it's no secret. 5 Powerplay points in 70 games doesn't fill that need.
Pesce is 21 years old and just played his rookie season. It's likely he eclipses 16 points in future years. That said, he is already a physical, 2nd pairing RHD. It's unlikely he will be a PP quarterback, or play on the first PP unit much at all (then again in Carolina we had Faulk, Hanifin, and Liles all play ahead of him last year, so there's a chance he would on another team). His 3 years in college he scored 6 points in 38 games, 21 points in 41 games, and then 16 points in 31 games. He'll never score 40 in the NHL, but I'd expect him to be at least a 20 point D, and potentially a 25-30 point guy. He's also 6'3" and weighs 200 lbs, so he has a nice frame. He has a lot of value and plays a really good physical and positional game, but don't judge him by his PP stats because he isn't a PP player right now.
Also, last year Pesce scored 4.57 PP points per 60 minutes. That was 4th best on the team after Riley Nash (lol), Rask, and Faulk. Pesce only played 65 PP minutes, compared to 185 minutes for Hanifin.
TLDR, Pesce is very good at moving the puck, yes. But he isn't a PP quarterback, and no one said he is. Consider him more of a 2-way guy. I'd hope he has a similar career to NHL player Derek Morris.
