I saw Nate "box", in the loosest sense of the word. But the point I'm trying to make isn't that Jake outboxed Nate (though he did do that, as unimpressive as that is), it was that Jake is willing to let his hands go. What held Logan back in his fight with KSI is that he fought scared and wouldn't try and throw. Jake lacks that same unwarranted caution and would be much more likely to go on the offensive against KSI. Considering Logan actually seemed to hurt KSI with only a few flush shots, one could think Jake, who is a much much better boxer than his brother, has more power and is more willing to use it would be able to knock out KSI.
