Actually, right now he probably is the best player in hockey. The only guy you could argue who is better is Malkin, who coincidentally plays on the same team.
Sports Illustrated did a survey of the NHL players and asked them who they thought was the best player in the League. The only condition was that they couldn't vote for a teammate. Arguably, no one is in a better position to judge "who is the best player in the NHL" than the players themselves. So who were the Top 6 NHL players as voted on by the players themselves?

1 Ovechkin
2 Lidstrom
3 Malkin
4 Datsyuk
5 Iginla
6 Zetterberg
Sidney Crosby was tied for 8th.
Also notice that 3 of the Top 6 are Red Wings.
There was a players' poll that Crosby DID win however. ESPN polled the players and asked "who is the biggest complainer on the ice?" The winner: Sidney Crosby.
