I think you missed the sarcasm.
It was the old classic let's turn it into rugby league suggestion.
Hell, you could open up even more space by just nixing 8 players per side, and de-power the scrum by limiting it to just the hookers and props. Maybe limit the time played per half to somewhere south of 10 minutes, so fatigue doesn't become too much of a factor and you just get constant flowing play. That would be a revolution.
Seriously though, the argument that reducing the number of players would open up more space -- a la league -- always makes me wonder. Would it? Or would it just change how defenses work in order to shut down space? If you watch any rugby league, particularly NRL, most of the game occurs within 10 meters of the ruck (or "ruck"), and all that vaunted space goes unavailed. That's partly because the 6-tackle rule limits what a side will actually risk doing with the ball, but it's also because they've just adjusted to close down that space as fast as possible.
You could go down to 11 players (gridiron), and it wouldn't make that much difference. We're talking about mainly a running game, and 11-player gridiron defenses close down the running game pretty quickly as well (and they get blockers).
So if those arguing for reducing players to create space were serious, they'd have to go with something like 10s or 7s, and just skip league all together.
