Last year, among d-men who received similar ice time, McQuaid ranked towards the bottom of the league in categories that people feel are important to positive on-ice contributions. The targeting of McQuaid in a trade signifies a continuing disturbing trend of the front office where they are valuing off-ice intangibles more than on-ice tangibles. Some people disagree with this methodology of evaluating players and are concerned with the trend we are seeing from the front office. With the understanding that 'this is a rebuild' and we are 'supposed to suck' this year, there is a fine line between 'sucking on purpose' and trying to better your team, but still sucking.
Do we have any idea of what role AM will actually play? No, but neither does anyone. Do we have any idea what return McQuaid will bring at the deadline? No. It can be surmised or predicted, but it is not known.
Thus, we look at the today of it. The today of it being the team targeted a d-man who was, to be blunt, horrific last year, trending downwards, and we are all okay with it because he's a 'warrior'. Well, at the end of the day, today, McQuaid is a negative add.
And that's why people are so down on him.
