Just watched Indongo's last two fights. The one was like a minute long but the burns one was pretty telling. He reminds me a lot of Paul Williams. His physical height and reach is annoying for his opponents but he gives it up a lot by lunging in with his shots. He also throws a lot of punches.

From what I saw, I really don't think he will give Crawford much trouble. Crawford himself has a pretty long reach and is much quicker. I'm not sure how good the chin of Indongo is but if it isn't great, I think he gets stopped. If he has a solid chin, he lasts the distance but will have limited output and lost most of the rounds.
