One on ones - he doesn't take advantage of his speed, it seems like he always slows down and tries to mesmerize the defenseman with his stickhandling. Or he should do the Kessel thing every now and again and just make enough room to get off the quick shot.
The hopeless situations where he's 1 on 2, 3, or even 4 - (re: 4 he's actually tried to get passed all of them, that didn't work). Once I noticed he just dumped it, but it was a bad dump in and rebounded out far, I like to see the puck dead up against the backboards giving the next line just a little more time as the defenseman have to go all the way back to get it.
Sometimes it seems like he's expecting his line mates to be reading his mind and throws out this really awesome pass to this nice big space - that doesn't have a Bruin in it.
Is anyone else noticing similar kinds of things? He has the skills all the way, 100%. I think it's just a matter of experience. I notice the Leafs fans jump out of their seats each time Kessel touches the puck, I'd like to see Seguin have more of that kind of an effect. Right now I think Marchand is the one who is the danger man in the offensive zone
