They have a lot of congruencies except for one major factor. Baer has the better chin and I think this is what would make the difference. Good fight for a while though
Both guys could bring down the walls of Jericho with their punches. Only one of hem could take a punch. That is most likely going to be the difference here.
Max could most probably take Ingo's right,as he did Schmeling's the reverse is not true. Baer connects at some point and the Swede goes bye bye.
I project that right hands would be thrown and landed. Baer as noted could weather Ingo’s bingo but Johansson would feel the hammer of Thor when Max slammed home his haymakers. Action fight but Baer KO 4.
