That first "but" is easy to write, but ultimately devoid of content. ALL achievements by ALL runners of ALL past and present eras have always ultimately been surpassed--if what we're talking about is times, that is. (Numbers of gold medals may be a different story. Those sorts of achievements often considerably outlast fast times.)
It's easy to make suppositions, based on the times Coe ran back when, about how he would have fared in today's races, but they're mistake suppositions. They neglect to take into account, among other things:
*) advances in training methods, shoe composition, track surface, etc.
*) how Coe, like all great competitors, would have responded to being surrounded by the faster competitors of our own time
Here's something to think about: ALL the current world best times, no matter how remarkable, will someday seem....well, quaint. Bekele, Geb? "Well," a kibbitzer like you will say in twenty-five years, "Bekele and Geb were great, but......" Much citing of current stats, superseded WRs, etc. "Geb was the Nuurmi of his day, but....."
Humph.
