I got what you meant by the Hallman comment, but that is literally his only claim to fame. It's ridiculous to even compare the two.
And it's just clear that Liddell is your favorite fighter. He's never been the consensus #1 LHW, he was the champ of the B level division, his title reign consisted of Randy x2, Tito, Jeremy Horn, and Babalu.
At the time, he was the face of the UFC, I'll give you that, but to put him in your top 10 all time fighters over 3 guys in the same division with better resumes. I just can't even understand your logic
