Webb is an under-hero, under-dog. He was top top and top hero just a few years ago. Some people want him to continue, and never stop, cranking out uber-performances. Webb just wants to run and partly be top-dog again but is willing to just run and enjoy. His fans put too much pressure in him to drop uber-times every race.
Webb is, in my opinion, the top non-competitive runner out there. He is capable of very fast times. You never know. His fans should just let him be. Let him run. Cheer him on. Stop worrying about his times. Lower the pressure.
