Makes sense to me. Chances are this fight will stay on the feet, where Silva is more explosive and dynamic. Even if it does go to the ground, Silva has the advantage there too. Brown's best chance is to survive the early onslaught and overwhelm him later but I don't see it happening. This is probably ending in RD 1.
Plus he's been out for awhile with a fairly serious injury.
Will make predictions for credits. Please, I'm so broke.
