I can tell you he will not get any sympathy in this group...they are a tough bunch. I would tell him that each time the kid says something negative to say to HIMSELF.. that's because you are threatened by me! Then let his play on the feild do his talking. I have never found a coach that cared how the kids talked to each other as long as they are winning. Men have a very different approach to these things and they just let kids work it our their way. I think it's actually a better way. Sooner or later it could come to fists. They will have a physical fight and then be best friends after! I do not get it by guys work like that!!!
