I think he is fantastic, and worthy of the #2 pick. If he was a few inches taller he would be competing with Lafreniere for the #1 spot. His imagination when he skates is something to behold. One thing he does differently is that he not only breaks a rush, but keeps possession of the puck afterwards. It is a risky, but potentially devastating trait for the other team, as their rushing forwards will be caught flat footed while Drysdale heads the other way, creating odd man rushes. At the junior level he dominates the puck-we'll see if he can do it at higher levels when the ice gets smaller, but with skating talent like that he has a shot.
Not sure of how good of a shot he has.
I guess a comparison would be to Makar or Hughes? As I watch him, though, one name jumps out at me when I see him play- Bobby Orr. Not saying he will be anywhere as good, but stylistically he has a lot of similarities, especially in the way he creates room for himself on the ice, then uses ALL of it, making the other players look like they are standing still.
Of course Orr could do all that at the NHL level, and was bigger and stronger. We'll see if Drysdale can hold up physically, and if he can withstand a heavy NHL forecheck. Orr could, with ease. Easier said than done.
A more low end comparison would be a bigger, faster, Spurgeon... if that's his floor, then you're doing pretty damn well.
