Every summer since Sidney Patrick Crosby's been old enough to skate and chomp into a Timmy's at the same time, winding all the way back to his Nova Scotia upbringing, he's strived to add some specific new tier to his craft. He hasn't always shared what those were, but there've been years where no one needed to ask. He'd follow a few months of intensive focus on faceoffs by instantly becoming among the NHL's most proficient in that facet. He'd follow another few months of focus on deflecting shots by instantly tipping home half his goals.
One might say he's a masterwork in progress.
