Joe has some serious skills on the ground and a solid background in taekwondo....Hackney was a killer back in the day and the octagon experience.....
LOL ... Hackney easy. 
Hogan all day. Takedown to ground game domination.
I would choose Hackney. If I am not mistaken, Joe got put through the porcelain by Stephen Quadros. That has to linger in a mans head if he is ever to engage in fisticuffs again.
Apparently the whole Rogan-Quadros ordeal looked a lot like Joe Calzaghe vs. Jeff Lacy until a beautifully timed headkick finished off a tired and worn out Rogan.
The fans :)
Rogan easily 
Could Joe handle the ridgehands? Tiger claws? Or the hammer fists? HHHMmm....Im not sure.
Hackney is a fighter..... Joe is a.......
Hackney was ruthless...just ask Joe Suns ball sack....
Don't know who would win, but I'd watch the shit out of that.
