All MA systems claim that they train kick, punch, lock, throw. If lock + throw = grappling then all MA systems are 50% grappling by definition.
How deep understand does one MA system have in grappling? It's very easy to prove by sending students to SC/Judo/wrestling/BJJ tournaments and see what the outcome may be. If a style can send their students to grappling tournaments and bring back the 1st place trophy, nobody will ever argue whether that style has good grappling or not.
Of you think that you have good
- striking skill, you should test yourself in boxing, MT, kickboxing tournaments.
- grappling skill, you should test yourself in SC, Judo, wrestling, BJJ tournaments.
It's just as simple as that.
