With Sean and other Stanford grads with Bowerman, there is a high likelihood of Grant Fisher will be with Bowerman after graduating.
The only other place I see him going is NOP. He did nominate Alberto Salazar for the ALS ice bucket challenge years back, but that could mean anything.

I personally Alberto will give Grant the tools he needs to succeed at the higher level, as his coaching is much more personal and precise.
I get the vibe that Bowerman is a survival of the fittest with high mileage. Great team environment, but I don't think that is what Grant needs.
