The more Damon moved, the harder it would be for Bobby to plant his feet and generate the power he needed.
Bobby liked to stay in one spot, get into a rhythm, and if Damon could disrupt that rhythm, he'd turn Bobby's strength into a weakness.
Damon had also noticed something else about Bobby. His head stayed right in the same spot, tucked behind that high guard.
Bobby had solid defensive fundamentals, but he didn't move his head. Damon knew what that meant, Bobby was relying on his arms to block strikes, not his upper body or head.
That was a dangerous habit.
Damon thought about the clean hooks to the body he'd landed earlier. He could tell they had made an impact, even if Bobby hadn't shown much reaction.
If Damon could keep working those body shots, he'd force Bobby to drop his guard lower and lower to protect himself.
Once Bobby started worrying about his body, his head would become an easy target.
