We're kinda onto semantics... If he had Suzuki's brain, yeah he could be a center. But that level of hockey IQ is an absolute rarity (he has to be a top 5 IQ player). He could be high end, and still not a good enough skater to stick there. He isn't as weak as Jost in that area, but the level of skater that a <6' center has to be in the NHL to be a reliable top 6 center is kinda absurd. They only way around it is with that elite IQ, which very few possess.
The worst skating/IQ combo and under 6' top 6 center in the league is Trocheck... and Trocheck is an elite skater. He may not absolutely fly, but he's near top speed in 2 strides, has amazing edge work, and is super agile. Dude can get up to speed and close or create gaps from nothing. Beyond him you have the Point, Hughes, and Bedard types who are in the very .1% of skaters. Suzuki is a rarity because only a handful of players possess his mind. You could put his or ROR's mind in pretty much any body and it would find a way. That level of IQ just can't be expected of any player though.
The deck is simply stacked against smaller centers. If you're 6'1"+ you can get away with a lot of skating flaws. If you're under 6', you have to be amongst the elite of skaters. Newhook is merely a good skater.
(All the slander against Suzuki's skating though, it is a bit hyperbole. He's definitely not a bad skater... just another good skater. One with absurdly high IQ)
