It's a general consensus that the best of the best meet at world cross, marathoners, 10,000 meter specialists and steeplechasers alike. It's a much deeper venue than Boston or New York or Fukuoka. Fair enough, Rodgers proved his prowess at that one world cross event, but you'll never convince me that he would even have placed in the top ten some ten years later, and I'll probably never convince you otherwise.
The difference in the international fields at world XC between 1975 and 1984, while most likely significant, is not quite as great as you make out to be. It wasn't until the very late 80s and early 90s, when Kenyans discovered they could make a good living at US road races, that the depth of the international fields exploded at all competitions. And an Rabat Morocco is quite a bit more accessible to the Kenyan, Ethiopian and other Kenyan teams than any of the places Porter ran.
While Rodgers might not have had the depth to face every year at Boston or New York, he did beat everyone 4 times each. Now call me optimistic but I'm sure at least ONE of those years, the best of the rest must have shown up. Actually it's more than just one but that's just piling on.
Porter never came close to beating the best of the rest at his event.
