It also depends on skill I am sure. You can still catch them by surprise and train to become stronger and faster. Plus with Cora now in his pack it might have given Derek the boost he needed to fight Ennis one on one. Plus we do not know how many betas any of them have killed for sure, so it could be had they killed a few more Derek would have had a tougher time fighting him.
