I usually respect your opinions Majorityof1, but I don't understand this.
Mansfield said "just about every way." Meaning there is at least one, and possibly even a few, thing(s) that Polak does better than Gunnarson. If Gunnarson is a better skater, a better passer, has better hockey sense, a better transition game, better offense, better defensive positioning, and a better stick handler while conceding physical dominance to Polak, would it not be fair to claim that Gunnarson is a better player in just about every way?
Polak brings less of a health question to the table certainly. It also remains to be seen how Gunnarson performs against the Western Conference, let alone the Central Division. I'd expect his offensive numbers to take a hit, but his defensive stats may increase a bit with the support he'll have from his teammates.
I also don't think that claiming one player is better than another in just about every way means that the second player is worthless. Sure, there are players who simply don't match up in a comparison: Karlsson and Weber spring to mind for example. But i think it's pretty reasonable to say the top third of the league is better than the bottom third of the league in just about every way. Heck, even plenty of good players are on the losing side of that equation when compared to great players.
I don't mean to sound harsh, and I apologize if I do. I just think we need to keep from over rating Polak. He was certainly an unexpected bright spot during the rebuild. Developed better and faster than anyone hoped. But he hit his ceiling a while ago, and the team has continued to get better while he hasn't.
