They have to both make it. First off assuming Datsyuk decides to go to Russia after next year (although I think he’ll give the Wings at least 1-2 more years after) He will end up within the top 12 in all time games played for the wings which isn’t the best, but he lost 116 games to the lockouts which would have put him at number 8 all time which could still happen if he stays longer. Point-wise he’s 6th all-time for the wings and pending how much longer he stays could unseat Federov for #5, and while it’s not the best measurement of performance he is #3 all-time for plus-minus. Take that and throw in the fact that he is the best 2-way forward of his generation and one of the best overall players in the game, 2 stanley cups, numerous selke and lady byng wins, has only worn the winged wheel, one of the most respected players in the game and there’s no question he belongs.
Zetterberg is a much simpler case as he similarly will probably end up below only Howe, Lidstrom, Delvecchio and Yzerman in games played, ranked 4th all-time in points assuming a reasonable drop-off, and be the third longest tenured Captain in red wings history behind only Yzerman and Delvecchio (assuming he plays until he’s 38 at least)
A couple other things… I can see the argument for Federov, but he may still make it when he does officially retire. I think there is still a bit of bitterness towards the way he left. Once all that dies down though, who knows. The Shanahan talk has to stop though. He was a great player and significant for what he provided in those cup runs, but he played more time away from us then with us, and both Z and Pav have already contributed more statistically then he did over a similar timeframe and there’s more to come.
