Aside from the lack of physicality and outward passion/intensity my dislike for him was intensified by a couple of things:
1. The analytic arguments --the way that people referred to so many stats that really mean nothing to me and do nothing but make me enjoy the game less as an argument in his favor made him even more unlikable for me.
2. Similar to the above, the attempts and contortions by many to convince people that he was actually "tough" despite all the evidence to the contrary was another frustrating aspect of his tenure here.
3. The fact that so many just couldn't get themselves to admit that he was simply a JAG was also frustrating. Now, I may be different that a lot of people as I probably consider a higher % of NHL'ers than most, to be replacable, but this guy was the definition of a JAG. Third liner - minimal to moderate offensive production, good defensively, not tough, no physical game.....I just described probably 3-5 guys on every team in the league. If you add in the other 1-2 guys per team that fit the description above with a little more toughness and now we're talking 4-7 guys per team. That's what a JAG is -- a guy who could go to another team and that team doesn't get better because of them and the team they left doesn't get worse because he left.
In the end, he just bored me to death and it's not because I don't "understand the game" or "appreciate the subtleties and nuances". If that were the case Dave Poulin, David Krejci and Dave Reid wouldn't be among my 3 favorite players of all time. Dave Poulin was a defensive forward that made it exciting. Krejci is as quiet and subtle as one can be on the ice. Reid was tremendously underrated, and not physical (for that time) as almost any regular, but I appreciated his overall game.
Lastly, for me, I have no problem saying that sometimes you just don't like a guy. Certainly the reasons above played a big part, but I can't say that I was ever a big fan of his, even when he was playing well in the first part of year 1. I didn't hate him, but I didn't watch him play and feel any kind of connection or get any particular enjoyment from watching him play.
Edit/add --- I will say that I don't think he was disliked as much as GD thinks. Admittedly, I stay far away from the cesspool that is Twitter -- but I think far more fans liked him or were at worst neutral to him than disliked him.
