Ok. BASIC submission defense is easier to learn than using them IMO. Nog's subs are not BASIC. It take years upon years to learn how to defend a flow like Nogs. Brock may be able to defend arm bars and Kimuras but theres no way he'll defend 3 straight sub attempts that Nog can throw at him.
A good post, since people act like "Brock Lesnar has leveled up, Brock Lesnar learned submission defense"
