It is difficult to maintain only a single thread for all the boxing matches. It might end up a messy thread. Every single match means a discussion on the skills of each boxer, their statistics and experiences, the odds, etc. If 5 matches are discussed in a single thread, the thread will not only become disorganized but also grow into a single spammy megathread.

I am in favor of a single thread per significant match. A thread is created if a certain match is worth discussing, if it is a mega match. After the match is finished, it should be closed.
