Any ideas? Teaching a new pro to relax

I have a young welter, who is 6-0, who just throws punches when he is slugging it out with an oppt, and leaves himself open to counters.
I told him and his coach to review the Joe Louis - Max Baer

The part I told them to watch was when Baer tried to force Louis into a slugging match and how Louis adjusted to it.

My kid has a stalker puncher style. He had a tough fight with a guy who forced him into a slugfest, so now I want him to learn, one, not to fight his oppts fight 2, I want him to relax so that he can throw inside the pocket if an oppt comes at him throwing heavy leather.
Any ideas?
