Soccer Plugins for editing videos

I'm a match analyst and i'm now trying to make use of Final Cut Pro X to help me doing a better job. I would like to know if anyone knows a plugin that has like 4 "dots" that i can move to follow a player (the defensive line). Somehow, what i want is something close to the plugin from Karsten ( here ) but that have 4 points instead 2 and that can free transform.

An example: click to see , instead having 2 black lines, i wanted to have a dot in each defensive line player and a line connecting the dots. Is that even possible?

Anyway, would like to know if there is any website that has particular interest in use final cut pro on football and that offers plugins for video editing on football.

Thanks!
