Good quote"Once you know everything there is to know about the A-side fighter, the show is only as strong as the B side’s personality allows."

I didn't pay attention who he wrote for; the only thing I would argue is he said a episode 24/7 did 465k viewers but the fight sold 1.5 mil so that's telling a 1 million or more didn't need to see 24/7 to watch the fight. So The All-Access numbers mean nothing to me.
