It's not beyond the imagination for Crawford to pull off a quasi-Griffith type close win with a move-bait-plant-counter approach and some serious holding on tight at close quarters to make it a styles thing. Tiger though was a lot better and busier than that declining, stiffer, potshotting, low output version of Canelo who lost to Crawford, and a lot better than anyone Crawford beat, which isn't true of the reverse. Not at a skill or size disadvantage at all, and far more tested vs historically elite fighters.
Tiger had to have the right opponent in front of him to look great. He could look pretty ordinary with the wrong opponent and I think Crawford would be a bad style matchup.
