in both vids the defender is trying to keep his legs between himself and the puck... if his legs contact the puck or he kicks the guy in the face i reckon its a foul.

in the second vid, you can see the guy actually trying to drop his knee onto the attacker, or prospecting hoping the attacker will swim into his knee... thats a tad more serious i'd think.

i've seen a guy do exactly that in a worlds game, twist to keep his legs in the way then kick when the attacker makes a move, hit him in the mask and swim off with the puck, and it was called and the guy sinbinned.
