I agree with the point about unconstructive criticism and that he is not a waste of a jersey but you give the impression that any criticism, whether merited or not, will be countered by you. I think you make some valid points but these can be mooted because you give the impression that you are blinkered when it comes Humphrey.
In my opinion during the match players are entitled to 100% support but after the game this is a discussion thread where the negatives and the positives are discussed. This will be the exact same situation post match in the dressing room. Stuart McCall and the guys will look at the negatives too and try and improve on these. The fact that we are top of the league, unbeaten and haven't conceded a goal all season doesn't mean everything in any of the 4 matches has been hunky dory. There has been negatives in all 4 games and there is nothing wrong with looking at the negatives because that's what makes good teams even better teams. I bet you even Barcelona look at where they can improve as scary as that may seem.
