This is all speculation, but i'm guessin Cormier really doesnt give a flyin F about bein da champ in either of the weight classes and he's jus fightin to mk sum bucks. Considering as u sd he's 34, been an elite wrestler most his life now so he's probably tired of the weight cutting and watching what you eat by now. he can stay on a avg diet not a krazy Dolce diet and stay competitive in HW. wit his level of wrestling and grappling im sure he cn beat most of the top 10 ufc hw's wit out trainin in wrestling, jus sum boxing and bjj defense to keep sharp.
If he really cared bout bein da champ he wld fight his teammate Cain, or he can stay a top 2 or 3 contender and jus mk sum solid bank on fights n avoid gettin too much damage n no overly aggressive training. Wha wld the payout difference be if he fought Machida or hendo/rashad winner and if he fought winner of jds/hunt?
