Lacking any real evidence linking diverticulitis to steroid use, fans then move on to speculating about how Lesnar could have "gutted it out." Or that he's a hair or two away from leaving the sport, thus proving that he's not a real fighter.
This is strange to me, because Lesnar is no stranger to adversity.
Lesnar could have quit MMA after losing to Frank Mir, but instead Lesnar hired a BJJ coach and learned from his mistakes.
When Lesnar was first diagnosed with diverticulitis, he could have easily walked away from the sport then, but instead decided to continue, and has since fought against Shane Carwin and Cain Velasquez.
In both of those fights, Lesnar again displayed a tough will by hanging around as long as possible.
Against Carwin, Lesnar was hurt badly, but he weathered the storm and came back from a situation where most fighters would have just thrown in the towel.
Against Velasquez, Lesnar was dropped to the ground multiple times, but got back up to his feet, still refusing to give up.
So while Lesnar might not have shown the greatest instincts in those situations by his poor reaction to punches, his will to fight, which is ultimately what we have control over, should be unquestionable.
