First off, ***** and moan all you want but the guy aint going anywhere. He'll be doing this long after your kid has aged out of hockey so chill. No one has their opportunities limited by tweets or one paragraph writeups.
Second, all evaluations are subjective from mini-mite tyrouts through NHL drafts. No one agrees. Get used to it, especially if your kids good/draftable. If he is, you and he better develop some thick skin because everyone has an opinion.
