Anyone attempting to defend a player using anecdotal evidence, really has no debate at all.
While EK has been the best player some games, he has been anything but the best too many games this season.
Blaming every player for EK's defensive lapses or high risk play is just refusing to accept the reality.
The team is inexperienced, EK needs to adjust his game to fit the circumstance.
This season EK has 20 points, 13 of them coming on the PP.
This indicates EK has been on the ice for 18 more goals against than he or his linemates have produced 5 on 5.
Of course all this isn't his fault, but IMO too frequently it has been this season.
I don't disagree with the notion that if EK had 15 more points people may not be so critical of his play.
However if he had 15 more points the Sens would likely have a few more wins as well.
Of course the reality is he doesn't have those points and he has struggled with turnovers and defensive coverage.
Karlsson's partner has a minimal effect on his defensive play. I'm not sure why people keep bringing up his defensive play as his own fault when debating the effect of his partner as it's not the big issue.
Playing with Phillips has had a big impact on his offensive game, which has led to more turnovers, and more agressive forchecks against him. the effect is quite noticable both with the eye test and in the numbers.
When Karlsson is on the ice with one of Boro, Cowen or Wiercioch, the line gets a 15% increase in CF/20 and 25% increase in GF/20 compared to when Karlsson is paired with Phillips. Phillips is a drain on the offense, there is no denying it. He's potentially fine as a defensive shutdown line, but he has no business on an offensive line at this stage in his career
Karlsson will always leave you a bit wanting on the defensive side of the puck; he's young and thinks offense first. If we can get him to clean up his game a bit, that would be great, but in the meantime, why are we pairing him with someone who is not going to be able to mitigate his deficiencies, and is a drain on his positive contributions?
Putting him with anyone but Phillips will likely result in more time in the oppositions end leading to more shots for, leading to more goals for. As a side benefit, this also means less time in our end, less shots against, and less opportunity for Karlsson to make defensive gaffs.
The only downside to playing Karlsson with anyone but Phillips is that Phillips will no longer benefit from Karlsson's offense. To this point, he's actually faired well garnering 83% of the GF while away from Karlsson, but that's unlikely to continue as it's a smallish sample, and he's been substantially out posessed by the opposition.
