Free agent backup Center or trade?

I think we need to think about another prototypical center to pick up in free agency because I’m thinking of a 7 game playoff series. Nets can beat Celtics, Cavs, Bucks, and 76ers each in one individual game, but can they beat any one of them 4 times in a series with the current roster? I don’t know. And I want to add someone in free agency because I don’t want to give up anyone in our current roster except g leaguers or a 2 way player or maybe patty mills

Who could that free agent is I don’t know.

What can the Nets get in a trade without removing our core 10 person rotation? I don’t know
