People tend to forget Zetterberg's 2008 playoff performance when he literally shut down the top 2 players in the world (Crosby/Malkin) AND set the franchise record for most points in a playoff season AND won the Conn Smyth. Z may no longer be a top 10 player but he sure as hell was the top player of his position that year and arguably the top 3 player of his position in the latter part of last decade. Add the cherry on top, he's the captain of one of the most successful franchises in NHL. They could not have set it up for him any better. If he doesn't make the rafters after those feats + his commitment of a lifelong contract on this franchise, then I highly doubt we will see any more jersey retirements anytime in the future. And I really don't even need to make a case for Datsyuk. The only thing holding his situation back is if he parts ways from Detroit. MAYBE.
Additionally people tend to forget that Federov did everything he did on an extremely stacked roster - a pre salary cap era. Don't get me wrong Federov was an outright beast of a player. But his feats were supportable by Yzerman, Lidstrom, Shanahan, Russian 5, and much much more. Who did Pav or Hank have to support their feats? an aging Lidstrom?
And even if we forget all these numbers. Z and Pav are adored by fans and the management. Babcocks called Z "the coaches son" type of player after he signed his major contract in 2009. If anything Z/Pav have a better shot at it than number 91; they're on excellent terms with the franchise and fans. But I do wish Feds gets it as well.
