But taijutsu has a heavy grappling element, it shares many roots with ju-jutsu, also someone who trains in and relies purely on taijutsu would have much different footwork and approach to fighting. I have seen heavy contact taijutsu sparring in person, and can tell you that it none of the principles were even attempted by this guy. Of course, in the thick of it fighting becomes a little generic, but, for example, MMA fighters who come from muay thai tend to be strong in, and rely on, clinch and leg kicks. Those who come from wrestling favour sweeps and G n' P, Bjjers the ground game- you get my point. Well trained principles/styles influence the overall approach/style of a fighter.
In this case, no traits of taijutsu could be found, ergo, he is either new to the art, or a really sh1tty ninja
