Mistake by Chad Dawson?
After Dawson was knocked down, Dawson tried to get up as soon as he could. At the count of 5, Dawson was already on his way up and was completely up after 6 almost 7 count. At that point, the ref counted up to 8 then asked Dawson if he was ready to continue .... Dawson was still out of it as far as being stable on his feet. Possibly even his eyes but I didn't get a chance to see that.
It must have been reactionary/instinctual but Chad should have waited a bit longer before attempting to get up. This way, he would have gotten an extra second or two since the ref would have gone higher than an 8 count before asking Dawson if he was ready to fight. Chad was also close to the ropes, he could have tried getting support while getting up but didn't.
Maybe it would not have made the difference but sometimes that is all you need to "look" OK to continue as far as the ref's standards are concerned.
