Some. Lyle was a good (not great) boxer in spurts, and could fight conservatively if he chose to. Nevertheless, he was a monster hitter, and quite ferocious. Overall, I would favour Lyle. He was the better fighter, but Lyle was nearly brought undone by Shavers (over-rated), so Id give Ruddock a moderate chance of an upset.
Pick-em... Both had terrific strengths and weaknesses... I could see ruddock KOing Lyle but I could just easily see the opposite...
