Am I missing something? It reads as though you're greatly undervaluing the importance of a top-4 defensemen. You realize we've been running guys like J.Brown, Zaitsev, Mete, Holden, Brannstrom, a plethora of AHL guys, Del Zotto, and the list goes on and on with guys of a similar ilk in a top-4 role.
We as a team and INCREDIBLY fortunate that a young 20 year old has been able to play like a top-4 defensemen this season or else we'd be in more trouble then we already are.
Yes young guys have question marks but it's not like there aren't question marks when it comes to the contract negotiations of DeBrincat. Sure he's an RFA right now but it'll be very soon where he's either a soon-to-be UFA or potentially the highest paid Ottawa Senator.
I would much much rather a young top-4 dman with contract control over Cat being the highest paid guy on this team OR seeing him leave this team for nothing/very little.
