I’m going by the definition of not having anything else in particular but an ability to take tons of puck abuse, using the NHL database (which only has blocked shots tracked since 2005-06).
In 354 NHL games, Nate Prosser blocked 572 shots. His TOI average was 13:45, and his blocked shots per 60 min average was 7.04. Nate Prosser scored 10-37-47 with his statistically best season being 2011-12 when he posted 1-11-12 in 51 games.
In 105 NHL games, Nick Seeler has blocked 162 shots while averaging only 12:45 TOI. Per 60 min, he’s averaged 7.26 blocked shots. In 2018-19, Seeler played 71 games and scored 2-5-7.
But the King of doing the most with limited talent is Greg Zanon, my favorite player ever based on his NHL 14 profile picture. I never would have guessed it, but over 493 NHL games, Zanon actually averaged a whopping 19:45 minutes per game and blocked 1279 shots, for an average of 7.83 per 60 minutes. Zanon scored 12-60-72 over his career with his best season being 2009-10, where he posted 2-13-15 in 81 games, wearing an ‘A’ for the Wild.
If you haven’t yet noticed, all of these played for Minnesota.
