Very hard for Ingo to get his right over and through that crouch defense. Not hard for Jeff to get that elephant trunked hook in. Horrible conditioning deficit for Ingo. Jeff had crazy conditioning, crazy hand and foot speed, Foremanesque physical strength, and he fractured two of Tom Sharkey's ribs in beating him over 25 rounds in 100 degree heat with his less vaunted right alone. The guy was a freak of nature. Ingo did nail Patterson with his Bingo in their second bout, but Floyd just wobbled a bit. Johansson was never able to put Patterson down for ten. I doubt he's putting Jeff anywhere near the deck. Mismatch. Ingo would stay away, retreat, retreat, retreat until running out of gas.
I generally agree with your posts,but,watching Jeffries against Ruhlin,Jeff looks very open to right hands. My hunch is Jeffries would be able to take the Swede's power , which means Ingo is in a world of trouble as the fight goes on.
