Dorian's side-chest in those pictures is fucking crazy. He more or less lost to Haney because of pec thickness ... but Dozzer's pecs a few years later? Holy fuck.
And yeah, in the so-called "front relaxed," Nasser looks much harder. But then, he's crunching down on his abs, flexing his pecs and delts and quads for all they are worth. Dozzer did little more than stand still, spread his lats and stand there looking as wide as possible -- still not "relaxed," but a fair sight from what Nasser was doing IMO.
