The main reason is that there is no match information in BB-Stats at the moment.
I think I have a function to import it but I don't have any pages the require it yet.
There is no real reason apart from I haven't had the time to implement it. I am doing all of this on my own and any BIG tasks like the match analysis stuff I can't really start in my spare time.
I will hopefully have a bit more time and structure since I have started a testing regime and have a bit more of a system in place to go through any major changes before they are released. Before I was making changes to the live website and then fixing any bugs on the fly. That won't work when I do big changes.
