I was under the impression that based on the antagonistic nature of your dialogue, your remark was referring to something rather negative. I stand corrected if that was not the case.
However, I am wondering about the point you were making through such a remark then... If you have nothing to say about his skills, just don't say anything at all ... or if you have a point to make, please have the guts to make it in a clear manner...
