Neither Granlund and Pulkkinen are 5'9, both are atleast 5'10 (178 cm). I guess you also haven't heard of Theo Fleury and more currently Brian Gionta (170 cm)?
Granlund was listed 178cm last year, but now he's listed at 175(smliiga) and it sounds about right. So he's 5'9, and he looks so SMALL.
So, Only 3 players... Gionta and Fleury + st. louis (5'9 and under) made it to the NHL. They're not centers tho, but then again Granlund can play as a winger. But Gionta's pretty fast, and i guess so was Fleury. But Granlund is so SLOOOOOOW. Granlund = Smliiga/KHL. You'll see.
