i personally think getzlaf tried to embellish the hit and caught his toe in a rut.
quincy looked like he gave a "bounce off" push to him, getz went for the duck (no pun) and added on to the impact.
once he realized (split second) he was going in awkward...it was too late.
but thats just me. look at quincey's reaction....he couldnt believe that getz went down so....funny.
