As much as the super-tall goalies get all the hype, it certainly isn't a requirement to win in the NHL.
I got curious as to the heights of the recent Cup winning goalies (then, I kept going beyond "recent"). Heights are from hockeydb.com...
- Binnington: 6'1"
- Holtby: 6'2"
- Murray: 6'4"
- Crawford: 6'2"
- Quick: 6'1"
- Thomas: 5'11"
- Niemi: 6'2"
- Fleury: 6'2"
- Osgood: 5'10"
- Giguere: 6'1"
- Ward: 6'1"
- Kiprusoff: 6'1"
- Brodeur: 6'2"
- Hasek: 6'2"
- Roy: 6'0"
- Belfour: 5'11"
- Vernon: 5'9"
- Richter: 5'11"
- Barrasso: 6'3"
- Ranford: 5'11"
- Fuhr: 5'11"
- Moog: 5'9"
- Smith: 5'10"
- Dryden: 6'4"
Matt Murray is 6'4". You have to go all the way back to Ken Dryden in the late-70s to find the next most-recent (and only other) 6'4" Cup-winning goalie. Murray, Dryden, and Barrasso are the only Cup-winning goalies in NHL history to exceed 6'2".
In fact, looking at that list, when there is a height-discrepancy between goalies in the Final, the shorter goalie usually wins. Post-lockout, it looks like 2009, when Fleury beat Osgood, is the only year that the taller goalie in the Final won the Cup.
Even though Murray is the tallest goalie to win the Cup in the last 40 years, he was shorter than Rinne and the same height as Jones in the two years he won.

Wolf might seem short when compared to guys like Rinne, Bishop, or Smith, but he's not that much shorter than Binnington, Quick, or even Kipper.
