PFL 4: 2022 Regular Season

I'd imagine they should announce the fights soon, this is probably the lightweights and the light heavyweights again.

The PFL should divide each weight class into two divisions of four fighters each, with each fighter fighting the three fighters in his/her own division once each.

At the end of the regular season, the top two fighters in each division advance to the semifinals, with the winner of one division fighting the runner-up in the other division.

And since every fighter in the same division will have had a head-to-head fight against each other, the tie-breakers would be far less, how shall we say, "Byzantine."

The extra points for stoppages etc. will only come into play if three fighters from a division finished 2-1 with the fourth fighter 0-3, or one fighter finished 3-0 and the other three 1-2.
