People tend to approach this fantasy fight, with the assumption that he would use the same style as he did against Dempsey, which was not his normal style.
I find it very plausible that he would make the same calculation, and use the same strategy, but should we assume it as a starting point?
I suspect that a prime Louis would walk him down and stop him eventually; thought Tunney would be a dangerous assignment. If Tunney used his usual strategy, Louis would likely get him quickly.
Tunney would jump right into a right hand and it would be lights out quickly.Tunney would be easily timed by Louis.
I would think that Tunney would be a tough assignment because of his movement fast hands and feet but I think Louis gets to Gene before the final bell
