^ On another note: I'm inclined to believe that if you break the skull then you break their "power". Perhaps that is all Derek realized, that he just needed to get inside their defenses and grab the skull and split it open. Removing the skull broke the "hold" over Scott and breaking one open destroyed the entire creature from what we've seen. So maybe it's not so much of a strength or power thing but a realization that the power or strength of a Beserker lies in the skull. Just my own opinion.
