Its tough to knock Barrera, I dont care for belts as much as I used to. It does help to market a fighter, but you get to a point when it doesnt matter. Marco is a prime example. His record is second to none and he is always active and will fight all comers, so what if he doesnt have a belt, he is top 5 P4P in most peoples minds without one.
As great a fighter Foreman was, sometimes he is way off when he talks. I remember when they had a P4P debate before the James Page/6 Heads Lewis fight, and Foreman said that Mosley or Tito would have to beat Page to be the #1 P4P champ, I fell out laughing, and then 6 Heads KOed Page. I like Foreman but you cant take everything he says to heart, and about the sanctioning bodies, they protected him as well. I dont know if you ever saw his fight against Axel Schultz, he lost easy but was giving the nod cuzz he was the champ and made them much more many than Axel would have. Once he was not the champ though, they turned on him and gave Shannon Briggs a BS win over Foreman in his last fight.
