anyone who doesnt have bergeron top 5 is a 'moran'... he has never clocked -under- 100mph in a team skills comp. that should be pretty telling right there. whereas a lot of the players being mentioned have never clocked -over- 100mph.
I'll agree with many others. Bergeron has one of the deadliest shots in the game. The reason he isn't more effective though is that he can't get it off fast enough. He's really not a great 5 on 4 player, but on the two man advantage, watch out because he'll probably score.
Chara, Souray and Rolston have to be top-3. I know these guys have the heaviest but they know how to use them too. You don't score as many goals as they have (for their positions) with slapshots without knowing how.
Guys like Lidstrom and Redden have seeing eye shots but I'm not sure it's hard enough to qualify for this discussion.
If we're adding 'intelligent' slapshots into it, we'd have to include Gonchar. He has extremely good placement and beyond that, can shoot it hard and accurately enough that teams have to respect his shot... which leaves room for that Gonchar-to-Crosby-backdoor-to-Whitney play.
And as for hard, Malkin shoots it hard... but he generally zings it far too high for it to be effective as a point shot. As a pure goalscoring slapshot, very effective, but as a point shot to create an opportunity, it's useless.
