Thompson has to make sure Arvin doesn't smoother.
If Arvin can get on the inside and let his hands go he might be able to beat Thompson, Yuri was able to do the same and Thompson has problems with that. Especially right now that Thompsons not jabbing Arvin needs to recognize that and get inside and work hard there.

For Thompson he needs to keep the fight at a distance start using your jab and keep Arvin at the end of it. Don't let Arvin get inside and out hustle you. Once you've got Arvin looking for the jab follow it up with a right.
