Anyone of these young guys that gets beat by Lagat and/or Abdi should retire. Sadly, I expect Lagat to beat all of them.
Derrick: Coach can’t coach marathon. Runner has never shown he can beat top level competition.
Fauble: Workout warrior better suited for half. Predict a crash and burn.
Ward: Injured. Best days behind him with Olympic glory.
Vail: See Ward minus Olympic glory.
Ritchie: Should maximize ability but not the same tier talent as Lagat.
Biwott: See Ritchie.
