At this point what will a win over Manny do for Thurmans legacy

[tokon]

In My Honest Opinion...Not Much!

Just like Pacquiao losing to one of these young fighters doesn't hurt his legacy at all because we all know he is older a past his prime despite still being really good

Correct but it's a very good payday for Thurman, and that's probably his main concern at this point.
It's not an easy fight for Thurman though.
