Strange sentence. Can you have 'elite running ability' without having endurance?
Unless by endurance they mean, being able to stick your hand in an ice bucket for ages, or let spiders walk on your face or something.
Michael Close would be a good example to answer that question. He may have elite running ability, but his endurance in a game sense was quickly sapped by body-on-body contact because of the strength imbalance between him and his opponents in his games so far. Bell has the body strength to maintain his running ability even after exerting himself in more static strength contests.
