Brook who was coming off a stoppage loss, a beating, a terrible eye injury and gruesome surgery to repair it, back down from 160 after bulking up to fight up there (and it's hardly the best kept secret that Brook always struggled mightily to get down to 147 before he bulked up). And on top of that, Brook was more than holding his own prior to the vicious head clash in round 8 which caused his injured eye (not the one GGG good boy'd) to swell up to the size of a horse testicle and it clearly impacted both him and the direction the fight took. And Brook would've immediately been haunted by the trauma he had to go through after the GGG fight after that happened too ''Oh god not again! Please don't tell me I'm going to have to go through that hell all over again'' ''Are they going to have to remove my eyeball via my mouth again to repair the broken bone? I can't do this again I need to pull out now'' ''Will I be able to escape losing the sight in my eye 2 times in a row if I don't pull out?'' ''I really don't want to quit but I can't go through that **** all over again. I can't risk losing the sight in my eye just to satiate the blood lust of all these tossers, it's my career and my sight in the eye on the line here not theirs'' So that just leaves career 140 pounder feather fist Algieri who was 1-2 in his last 3 fights Lemons Peterson was another career 140 pounder feather fist who should've been 1-2 in his last 3 fights 42 y/o senior citizen feather fist Bundu Algieri and Bundu aren't just feather fists, they're Paulie level feather fists That is Spence's resume in a nutshell. To be fair to him he is rather adept at bashing up Paulie level feather fists and little Paulie level feather fists coming up in weight and now he's fighting a blown up 135 pounder and get this folks, even though said blown up 135 pounder has come up from 126 they will be, at worst, the second hardest puncher career 147 pounder Spence has ever fought But Spence is P4P
