If we look back to the Robert Whittaker vs Colton Smith fight, we saw a fight that stylistically was a tough one for Whittaker. However, Whittaker kept his lead hand low, ready to get an undertook should Colton shoot. This, combined with a powerful uppercut (which McGregor favours too) and some knees, make for great deterrents.
McGregor hangs his hands low a great deal, but also likes to throw a whole load of flashy kicks. If he could resist the urge to throw high-risk kicks, he could make for a tough target to take down.
