As I said before, healthy questioning/skepticism is almost a necessity in today's world. However, in reading these posts, I can't help but be reminded of an underlying anti-Rupp bias that began when he did things different in high school and has continued in some ever since.
Case in point,
1. Rupp is criticized for using gadgets, gizmos, etc. and his performances are questioned.
2. Rupp goes after an American 10k record.
3. A guy who has never run a 10k before, blows by Rupp (whose methods etc. have already been questioned) with an amazing last 800-1000m becoming the first non-African under 27 minutes and crushing the American record.
4. Said athlete is praised for his amazing performance with very little, if any, questioning of his unprecedented performance.
I have no doubt that because Rupp has never been perceived as some as a true "blue collar" runner who relies some on gadgets and gizmos that when he does amazing things people somehow assume it is because of some possibly/likely shady gadget/gizmo/method. When someone that the jaded "due it the old fashioned way only" crowd lays down a similar performance they get the benefit of the doubt because they've always been in the "true blue collar" club.
Again, I don't know who is clean and who isn't. Who is doing things that are illegal or unethical. However, I am 100% convinced that there is a general behavioral/methodology/personality bias from some regarding Rupp versus others.
