Are you f***ing kidding me?
Datsyuk is borderline top 100, if we're being charitable, while Sid is top 5-10. Since Crosby's IQ is probably his strongest trait, it's a bit ludicrous to suggest Datsyuk was his superior. I take Datsyuk's defense and stick-handling over Crosby's and that's about it.
Like all the other two-way darlings in the NHL, Datsyuk is one of the most overrated players on HFBoards. The way people talk about him, you'd think he was a 100 point Selke winner every year of his career, even though he really only had a roughly two season period where it wasn't ridiculous to mention him in the same sentence as Crosby and OV. It also helped that he spent a good chunk of his career playing with a HHOF-stacked roster of superstars in Detroit, where more often than not he wasn't even the best player on his team. I highly doubt he'd have had the same success playing on a thin Pittsburgh roster.
We never got to see peak Crosby for an entire season but 2011-2014 Crosby was on a whole other level, if you're comparing him to any version of Datsyuk. This is a guy who lead his team in scoring, while only playing half a season.
