Chabot + Zub + Holden + Hamonic had a combined +2 in games for the Sens last year, while the games were lost with Mete, Zaitsev and Brannstrom laying a -43 combined egg. Demoting or removing those anvils will really help the corps.
I wouldn't overpay for Chychrun, given that we hope Sanderson can be a valuable top 4 late this season or early next. While Holden is a little old at 35, Hamonic is just 31, so this group should have a very nice top 4 through the Giroux years, bordering on way above average if Sanderson matches his promise.
