Will Cung Le be the man to bring the sidekick the respect it deserves? Sherdog's pictures of his fight with Tony Fryklund show Le landing several sidekicks that look like they really have some oomph on them. Almost no one else has used them yet in MMA, but perhaps that's because no one knows how to use them properly. There was also a point at which no one had used a back kick or a spinning kick, and although there has yet to be a proper hook kick knockout, the back kick has shown its effectiveness in several fights.
Maybe soon he'll even whip out the skipping or sliding side kick ala Bruce Lee.
