His wars with Holy and Bowe prove otherwise. Shot Bowe got a hellacious beating from Golota in both fights, both legal and illegal punches, and he fought back while most others would have quit. If ever a HW got beat up in the ring without getting KOed it was Bowe, by Golota - the effects of it (severe brain damage) were seen shortly afterwards...
Bowe's a fairly solid contender for glass hearted American of the day. But his lack of heart pails in insignificance when compared to the gaping casm in the chest of one man. Andre Dirrell - Glass Hearted Ameribum - Champion Emeritus.
Bowe is lucky to have had a couple of great performances that everyone judges him by now. In reality he should be judged on his whole career, including the fights where he got his arse kicked. His performances against Golota could be considered a regression to the mean rather than a result of laziness and ill discipline. I think Bowe is hideously overrated these days :-(
Golota dominated a slightly past it Bowe. Golota vs a Prime Bowe would have been closer no doubt, but I would still pick Golota to win.
Some argue he was overweight for the Golota fight. But past-it probably wasn't the best phrase to use.
I only recall the story that they sparred two rounds, Bowe was knock down in both rounds and quit....
GTFO Bowe had 2 wars with holyfield where he went toe to toe with a prime holyfield. The 3rd fight was still pretty good even though evander wasn't 100%. He did ducked lewis.
