If you're a boxing nerd, there's a guy on youtube with a great channel breaking down fighters/fights. Ive almost gone through all his videos. Theyre really good.
for example, lara canelo, or any of the floyd maidana ones , floyd judah adjustments

If you have 10 or 15 minutes to spare, id recommend you look around his channel. GGGs footwork, crawford, even some classic stuff there too
Edit. The lara one didnt post but its worth your time
