I don't think Jack's issues are just him being tired, but I think its playing a part. I know he is getting ton more attention from opposing defenses, and it is freeing up David a bit more. But its quite clear that he's exhausted out there and can use a bit of a break. Nothing wrong with starting him on the bench for this one. Khiry has fresh legs and puts in a ton of work defensively. Have him start out there on the wing and bring in Jack if necessary.I don't agree that we are at a crisis mode - other than in having too many players hurt and suspended. I also don't agree that Jack's issues are due to being tired. I do acknowledge that the team in general has been through the grinder the last few weeks, but that's true of all the teams.
There is a short break after the game in New Jersey. Give them a few days then.
Sitting Jack at the start is not "not taking NER seriously". Its a move that IMO would be better for us in the long run, and actually may be better for us against NER.
