First off, Rupp was primarily a racer, he only had 3 pro races where from gun to finish the the focus was clearly on time and in each of those cases he ran very fast. His indoor, mile, 2-mile, his indoor 5K and out door 10K. In all of his outdoor 5ks, there was only one, perhaps 2 legit opportunities where he should have run a much faster 5k and that's the one where he ran a12:58 and 13:02, which are fast times. You don't get credit for what you didn't do, but Rupp's 3:50i mile and a 12:49 10k almost certainly he could have run much better than a 12:58 5k.
Jakob Ingebrigsten 13:02 5K to Rupp's 12:58 5K is a comparision between athletes, there is no comparision between coaches. Coaching athltetes to WMMs victories won mutiples World and Olympics medals, Alberto is without a doubt among the worlds greatest coaches. Btw, none of this is meant to take away from Jakob Ingebrigsten becasue is probably going to win some global championship medals, but to compare Alberto to Gjert is stupid.
