Does Jacobs have one of the worst chins?

Quillin should stop him.

Here's to hoping he gets stopped soon. Especially after the bs he pulled this weekend.

Apparently Martin Murray knocked him down hard in the amateurs too.

Jacobs kills himself to make the weight, I think that's a primary factor. It's not that he just got knocked down, he didn't recover that quickly for it being a flash knock down.

I hope he doesnt fight GGG, seriously. Imagine if GGG lands the same right hook that he landed on Ishida.

Not making fun of him, but if it was just a flash KD - no problem. But Jacobs had no legs like for 30 seconds after he took that punch and thats a main evidence of the glass chin. Ask Khan. Not to forget that Mora has 26% KO ratio. Jacobs chin is even worse than Khans; Jacobs probably the worst famous chin in boxing today.

Among top guys in any division, it is up... down there. I'm sure you can find some guys who take a shot worse, but getting dropped solidly by Mora is a pretty bad sign. Being stopped by Pirog isn't too big a shame, but he did one punch KO him with what looked like a pretty standard, albeit perfectly executed counter right hand. He definitely isn't as bad as Khan, but I think we will see him get sparked again in the near future, providing he fights a top guy (big assumption).
