Rock Lee is faster than Tayuya and he could score with his taijutsu moves. However, Tayuya is a very smart girl and she is the worst possible enemy for someone like Lee. She's a genjutsu specialist. Shikamaru managed to get out of her genjutsu, but unlike Lee, Shikamaru's IQ is over 200. Lee is pretty stupid, I doubt he can do something against genjutsu. Also, don't forget Tayuya's summoning jutsu. She could distract Lee with those and prepare a strategy or just hide and use a genjutsu. How will this end?
