I would say draining effects overall sharpness (speed, reflexes, movement), and what type of fighter is Sergio one that is heavily reliant on speed, reflexes and movement. Hell even his power comes from those attributes.
Now the question is at 38 years old will he only suffer marginal decline moving down like that I would say history and reason say otherwise but I guess people count him him beating the odds like that.
