There have definitely been instances where fighters looked dreadful weighing in and came out and won, but there are a few things to keep in mind;
-I struggle to think of anyone who looked QUITE as bad as Calvillo did. I rewatched the Ladd weigh-in and while she looked rough, she looked at least three times as good as Calvillo did. Spoke and walked normally, managed to pose and flex.
-Most fighters who weighed in poorly but won did so against opponents they were vastly superior to. Not the case here.
-Related to the last point, most such fighters had the option of taking their opponent down and winning there, as Ladd did. Calvillo's path to victory, as I outlined yesterday, consisted of frustrating Botelho with her movement and beating her to the punch for 3 rounds while avoiding any big punches or kicks. That's asking an awful lot for someone who looked so dreadful at weigh-ins.
With that in mind, I put 3.67 units on Botelho at -165 and about 1.4 units on Botelho inside the distance at +230.
