I didn't mind Goligoski's "weakened" game and figured it would take at least half a season to adjust. After all, he was in Dallas just over 5 seasons, so to expect the same production out of a D-man is raising expectations a bit.
In terms of McGinn, he never has been too consistent in his career. He was inked because it looked like he was improving quite a bit 2015-2016 was his best season and he played with two teams). Also, if we look at Buffalo and Anaheim, they both tend to be more offensive-minded teams, so coming here, he was probably at a disadvantage (and overpaid). Admittedly, the bulk of it probably falls on him, but we were switching linemates quite a bit last season.
All I can hope for is that some new strategies may improve production from some of those who struggled; of course, those changes may reduce production for others as well. It will definitely be an interesting season.
