"white supremacists"? WTF?
Anyway, please explain "plateaued" and include some factual and or knowledgeable info as to why you think this. Also, as with many people who post opinions on this board, be sure to know what your talking about as it does help legitimize your opinion. People who know the sport can easily filter out those who do not.
That being said, Jakob's ceiling in the 5000m and 10,000m is really high. I believe he's put in a tremendous amount of foundational work over the past few years with the priority being speed endurance (1500-Mile) development, but has not emphasized nor neglected strength development (3000m, 5000m, and Cross Country). Once Jakob transitions and commits to the 3000m, 5000m, and 10,000m we will see another breakthrough. I would dare to bet he definitely has the potential to set world records at the longer distances. He could scare the 1500/Mile world records as well, but he needs to do so very soon. In the end, the 5000m and 10,000m will be his best races.
Cheers!
