As I've said before, one of the strongest attributes BJJ offers is its guard. On the other hand, it can also be its weakest. BJJ players all too often rely so heavily on pulling guard completely neglecting proper takedowns or throws. Conditioning only one way creates large holes in your game and the best grapplers are going to be those who cross train in other arts as well as in positions they are not good at. This carries over from sport grappling to self defense situations where pulling guard, or going to the ground, is the last place you should want to be regardless of your belt color.
If you don't believe me, take it from JiuJitsuPedia and Judo Black Belt Mark Hidalgo. Today, he goes over the Morote seoi nage which is a two arm shoulder throw that works great for self defense, Judo and BJJ competition.
