I saw a report that he is, in fact a slow but he has good edge work that helps make him at least a little bit elusive to get that slight opening he needs to make a play.
I've had a ton of time recently to watch shifts video so I went hard in on Perfetti because of
@NotProkofievian crazy love for him.
He is actually quite the dynamic skater. His top end speed needs work, it's average, but his startup is not. It's sprinter quality. He gets to top speed very quickly and surprises guys all the time. It allows him to create space and to break free.
His edge work is superior. He can go from forward skating to crossovers to mohawks to reverse spin back to forward again all while stick handling guys and retaining possession of the puck. It's all incredibly smooth too.
He is strong on his skates and very well balanced. He doesn't get pushed over.
His shot is Kovalevesque. Release is phenomenal and he doesn't miss. Loves shooting high, shortside. That's a really tough target and most players over shoot it, but he makes it look easy.
Skilled passer and quality vision too. Not a one dimensional shooter at all.
He's small but he battles. He's similar to Suzuki in that regard.
His average speed is below average for the NHL though, so it's a MUST to work on. Add in bigger & smarter players too, they won't be as easily fooled by his trickery as they know how to peel guys off, and take time & space away.
At worst, he's a Mike Cammalleri type. A PP specialist who'll score goals and make plays.
However, the potential is there for a Martin St. Louis or a much better shooting Mitch Marner type. The high skill level is there. Needs to do some leg training.
