Brassard earned 3.7 mil last year. His cap hit was 3.2 mil.
Zucc won't get 5 mil and I don't see how you can possibly compare him to Moulson or Cammalleri, both of whom were UFAs.
Even Ennis is a poor comparison. Ennis has been a regular NHLer for 4 years. Zucc has played only 1 full NHL season. Granted that one year was better than any of Ennis' years, but that's all the more reason why they aren't a good comparison.
The Rangers know how much cap space they need to get these contracts done. There is little chance that Brassard won't be on this team next year.
Also, Kreider as a pivot? He hasn't played center since high school.
