I think it matters a bit to at least have someone there to help you with tempo. I know running is easier alongside someone, and there’s no drafting there either (not at my speeds, anyway). Also, picking up the speed after the crest is easier on the wheel of someone with fresher legs. It all adds up, and if he’d been alone Roglic might have lost 10 or 15 more seconds, probably wouldn’t have got back to Martin’s wheel, etc.Having a teammate doesn't matter too much at this speed and no wind
