i think block and stall moves are freestyle too. Clipper, eclipse, v-stall etc. Also, i think freestyle should have some room for creativity. Lower, grounds, upper and sits are the main categories ofc but fs is not restricted to those things only.
Imo, finger spin is ok if used to start a trick like spinning v-stall, spinning head stall etc. The other tricks on the website like hypnotiser, never-flat, slip n slide etc are useless haha. That is definitely basketball. Nice tricks, but i agree it is basketball.
But to be fair to him those tricks are good in lp for football freestylers too.
The pen tricks, t-shirt tricks and breakdance tricks are also good in lp.
I like that website though. Most of it is cool stuff.
