Arlovski might have a much better chin with boxing gloves and an 8 count to recover.

There's a big difference in going to a neutral corner and letting your opponent recover rather than jumping on them and continuing to punch them when they are down.

I think we would see a whole lot less recoveries in boxing if the other fighter kept punching them when they went down. Arlovski is lacking a bit in the chin department, but I don't think it would be nearly as big a hole in boxing as it is in mma.
