Off the top observations.
1. Number one is that despite Jakob's stoic demeanor regarding his opinion of his competition, he wouldn't have told Nuguse to stick with him unless he could obviously see Yared's raw potential. Jakob is aware Yared has the goods to be one of the best ever or he wouldn't have thrown the stick with me challenge out there like that in the first place.
2. Jakob is consistent in stating its hard to run from the front and he would be better if he had other runner's take his load. Read: I am the pacemaker but the more people I have to run with me like Yared, the faster I will be.
3. He's clearly in 3000 world record shape but it won't happen tomorrow because of what he did today. However, he's most likely still going to win too just to be him.
