Thurman would have taken Spence far more seriously than he took Pac, and would have been more focused, but Spence still whoops that ass.
I think Spence vs Porter will be telling. Thurman and Porter seem kind of even to me a few years ago. I dont think Thurmam beats Porter right now.
Pacquiao is not the man at 147 unless he beats Spence or Crawford. Pretending that a 2019 Thurman has any kind of chance of beating either will not change that.
