Though Spence Jr. may be undefeated, I also do think that the fight will not be easy against them. If I were to bet, I would somehow bet my money on Ugas due to the talent he showcased against his fight with Pacquiao.
Thinking also the same if the odds are great. Since Ugas is the sure underdog, I'm expecting at least an odds between @3-4 regardless of what he has shown during the fight with Manny Pacquiao. Ugas surely learn some lessons after a fight with a high-class boxer after defeating it. Ugas will treat Spence as another achievement if he passed on it that's why he will be seen to be expected more aggressive here compare to the latter.
