Yep, sounds like that's what happened. The outsides cooked before the heat had time to penetrate to the inside of the patties. Try using less charcoal and pushing the coals over to one side after they have turned red. Then you can cook the patties off to the side with the lid on before removing the lid and moving them to directly over the fire to finish with a nice flame-broil.
Cooking with charcoal is tricky and takes a LOT of practice to master the art.
WhatchootalkinaboutWillis? I've always been better with charcoal and flame than over a stove. I never burned anything on a grill, but I can atest to at least six times I've set off the smoke detector in the kitchen...
