I Glen summed it up himself when (I believe after the Jones fight) he said, "I'm not the best. I'm just the guy who's willing to fight the best." Of course, a lot of boxers might claim to be willing to fight the best, and they might even mean it. The difference is that Glen Johnson has been able to consistently perform at a high enough level to put him self in position to fight the best.

I kind of think he is similar to Larry Bird in the NBA. Bird had natural talent, but wasn't the most gifted athlete in the NBA. He achieved his greatness through an unparalleled commitment to practicing his craft. Glen is very similar, and is always the consummate professional.
