1. I agree that I would resauce the chicken with warm sauce about 25-35 minutes out depending on what temp you cook at and/or sauce thickness.
2. When you take it out of the butter...that is what the light colored sides indicate to me, I would re-season the bottom and sides of that chicken so that it is a bit more uniform. Judge is going to taste the bottom and side of the chicken first and possibly only.
3. I'm going into hiding after this...and I'm sure it's the camera (insert emoticon), but the chicken looks orange. I would want bbq chicken to be more of a BBQ Red color.
From the looks of it...that's what I would say.
