There are some pretty bad dudes out in the UFC. But can you imagine Lennox with 4 ounce gloves hitting somebody? That shit would be horrible to watch. Ground and pound aside, anybody that got caught with a Lewis flush shot would be put on life support.
Lennox Lewis hasn't been training for years but he's a fucking big guy. He's also very strong. Ortiz might beat him now, but if he can't beat Chuck Lidell how's he going to beat Lennox Lewis in his prime?
