In my opinion, if the evaluator comes out with that "concern" in that manner, then he's the one with the problem. I wouldn't take it with a grain of salt, just listen and say thanks, and get the hell out of Dodge. I would rather have my evaluator say "the coaches were saying something along the line of you were talking too much. Just something to consider." That would show support on my evaluator's part, and show he's not trying to throw me under the bus.
