I didn't know who Tank Abott was until I looked him up after reading your posts. I've only been watching the UFC for the last couple of years and haven't been able to watch it consistently because it's not on TV all the time, and since I've moved out of home I don't have satellite.
I just watched a few of his fights on youtube. Tons of mongrel in him, he's "talented" in his own bar fighting way, but he's good because he fights with a lot of guts and determination. I watched the fight where Kimbo Slice TKO'd him in the first round, definitely a tough dude to take the punishment he did for so long without dropping.
Reminds me of Roy Nelson.
It's awesome to see those guys that don't look particularly fit just smash the monsters, haha.
One of my favourite fighters is Forest Griffin. The fight between him and Stephen Bonner was crazy, his nose looked absolutely ridiculous! His forearm was also snapped because he wouldn't tap out. So much guts.
