"Brock wasn't healthy," Heyman said.
"I don't think Brock has truly understood nor accepted the severity of the illness that took him down. They did blood work on Brock and they found out he wasn't healthy for many, many years. His body was fighting this affliction off and using so much of his energy.

"The Brock Lesnar who stepped into the cage with Alistair Overeem, he was at 50, 75 percent. You're going to fight Alistair Overeem at 75 percent, Cain Velasquez at 75 percent. He fought Shane Carwin at 75, or 60, or 80 percent, but even at 95 percent against Shane Carwin, you're at a disadvantage."
