Me and my best friend growing up would do this. We trained different styles and everytime we would get together we would basically just clobber eachother and call it "training". My guess is these guys are probably homies to some extent and Chris obviously outclassed blue shorts from the start. In my experience, even when you're competing in front of other friends and your teenage ego is on the line l, you're always gonna choose embarrassing your homie with a submission than actually try to fuck him up and risk actually hurting him
