At best he wins some poses, most he doesn't. Fox wins front or back double-bi easily; nothing compelling about Haney's front or back double-bi. FYI for those who don't know, the pose requires good arms. 
Haney easily wins both the frony and rear biceps shots . and FYI the pose also requires a back , clavicle width , size ..stop cherry picking what part of the judging criteria you think he wins while ignoring the rest ..Haney's 250 pounds crushes Fox 210 in any pose
backs are night & day , Haney has among the best , crushes Fox in width , thickness , depth and detail , Haney much better taper , when all factors are considered Fox doesn't come close to Haney
