To your points.
Dominated? A fight that was clearly 2 rounds a piece and the deciding round 3 was extremely close, you have a very funny definition of domination. That was as competitive and close as it gets lol. And Ankalaeve is an elite LHW.
And you really can't hold the Israel KO loss against him. At MW he was compromised with the weight cut, since moving up to LHW Alex's chin is rock solid. And e just made a defensive mistake, it can happen to anyone. He's been in there with some power punchers at LHW like Jiri, Rountree and had no issues.
Jan was a champion level fighter, noting wrong with going to a split decision against him. We saw Gane fight Volkov to a split in a fight many felt he lost, and Volkov is not an elite HW.
There really isn't much to be confident in here one way or the other. I think Gane has some advantages, but not the points you mentioned.
