Half of the people on this thread must be trolling.
Jakob clearly has the better pedigree. He is younger, has better personal bests in all events >800m, has more global outdoor medals in the 1500m (1G2S in the 1500m vs 1G1B), has a better head-to-head record in the 1500m, and is also dominant in his second event on the global stage whereas Kerr is about 1.5 seconds away from a top 800m.
Kerr beat Jakob in the most recent global final in the 1500m and has since run some very impressive races which show his win is not just a fluke.
It will be a good race to watch. If Kerr wins again and puts up some big times, it might change the conversation in years to come.
