I do agree, his slap used to be very accurate, this season it was atrocious though.. Pavs the opposite. He's got a terrible slap shot accuracy but an amazing wrist shot. Don't blame him, he's not much of a shooter and wrist shot usually complements you're stick handling ability, which makes sense in Pavs case. As for Z, I do believe it's confidence and speed, if he can get in the groove of shooting some mean shots, he can definitely achieve 30+ goals. I like our first line and I think next season can be a good one for both Pav and Z's point production. It already improved this season hopefully they maintain next season.
I agree that Pav has a better wrister than slap shot and vice versa for Hank.
But Pav's shot, in general, is fairly inaccurate (in my opinion). I know that he can absolutely pick a corner sometimes (see game 4), but many times Pav will have an open shot and blast it wide and/or high. Then again, he is not a sniper.
