I would have to say nhl cause you are always moving and hitting other people at high speed
The hardest official shot in the NHL was registered by Zdeno Chara at the recent all-star skills competition when he had a shot of 105.4 MPH.
Ted Williams was quoted several times as saying hitting a baseball was the single most difficult thing to do in sports.
Kicker of course. Kicker makes car audio products, not home theater subs. The term 'hardest hitting' isn't a measurable quantity. For the sub with the most power, try the Tannoy TS212iDP, a subwoofer with 1500 Watts and 2 12" drivers.
Yes and no. Billy Coutu was the first player to receive a lifetime suspension from the NHL. That suspension was for slugging a referee, not a coach.
Definitely line-backer wise it's either Ray Lewis or Patrick Willis.
