Probably because, like you, I am not on a basis with Bill Rodgers that I can stop by his place. Also like you I have near head him say that he thinks Boston is an aided course. I have read an interview with him in which he mentioned how it would have been nice to have have raced on a course like London or Chicago in his prime to see how fast he might have run. Can't think of why he would say that unless he were more inclined to think it was faster but that's neither here nor there.
Regardless, trying to give me an example of people who have run their fastest at Boston isn't really helping your argument much. Sure in a year like 94 you are going to get some great times. On a cool day with no wind at all, however you are still going to get a slower time at Boston than you would get at a Chicago.
The simple fact remains that even with this "aided" course and the wealth of talent that has come back here over the years, you haven't seen a world record at Boston since...God I don't even know when now. The 40's? The 50s? There have been dozens of sub 2:07 marathons run throughout the world and yet not one of them happened at Boston, not even in the "insanely" aided year of 1994.
A good friend of mine actually DOES run with Bill Rodgers on a regular basis. Maybe I'll ask her to ask him and see what he thinks. I like my chances.
He seems like a pretty honest guy, so I like my chances, even though, with his fastest times (and only sub-2:10s) coming at Boston, he's not exactly impartial. I know he's had discussions on the topic with others (including Derek Clayton, who was disdainful of times recorded at Boston).
I didn't just "try" to give "an example," as you stated. In fact, I think I accounted for every sub-2:10 marathoner in U.S. history, although I didn't bother naming guys like KK and Hall who never ran Boston. (Jerry Lawson may have run Boston at some point, after his peak. I'm not sure.)
As to whether Boston on a windless day is faster than Chicago on a windless day, I take no position on that. That's not what determines whether a course is aided. In the case of Boston, the course, which is not only point-to-point but is also significantly downhill, will be faster than a loop course under certain conditions, including the conditions that existed in '75, '78, '79, '83, and '94. The same is true of a number of point-to-point courses that have no net elevation loss whatsoever, such as the old Mardi Gras marathon, which was just a flat, straight run across a very long bridge. When there was a prevailing headwind, the times were much slower than they would have been on relatively fast record-quality courses. But when there was a prevailing tailwind, the times were absurdly fast. It was an aided course.
As for world records at Boston, of course there haven't been any set in recent decades. Under modern standards, there can't be any set at Boston. Joanie, however, did run three minutes faster than the world record at Boston in '83. And DeCastella ran faster at Boston in '86 than he did when he set his world record at Fukuoka in '81.
