I have to give the edge to Fedorov due to his flair
Fedorov > Datsyuk. More goals, more points, faster/better skater, better playoff performer, and based on Bowman's assertion that Fedorov could have won a Norris Trophy had he played defense for an entire season, I'll give Fedorov the nod on play in his own zone as well. As for physicality, both possess(ed) the goods to give it as much as take it, but Fedorov showed this side more often. As electrifying as Datsyuk is, it's easy to forget that Fedorov possessed immense amounts of flair as well in the 90's due to how he is poo poo'd by fans because of how he left the team.
I believe the minimum amount is 37 pieces
