If he hits the market, I do genuinely think Ottawa would make a serious push.
We'd have 33mil on a 14 man roster with only Tkachuk, Batherson and Zub as significant expiring deals... guessing that will cost at most 12-14mil, and probably closer to 10.
Most importantly, Hamilton would shore up our D for a long time... by the end of next year:
Chabot - Zaitsev
Sanderson - Hamilton
Brannstrom - Zub
J. Brown/JBD/Thomson/maybe Gudbranson/maybe Reilly
Zaitsev is a little over his head on the top pair, and Sanderson may still be a little over his head as a 2LD, but adding an elite RD would really solidify our future.
