Once you start quiting, it gets easy to do it again. I thing he should quit walking into the ring so we don't have to watch him quit in the ring and then blab on about excuses and refusing to give his opponent any credit for kicking his ass afterward.
Actually he gave credit to Postol saying he had a good night and could execute his plan to the perfection plus he admitted he lost to the number one in the division not some journeyman.
