Don't count this team out against the Nets. Tatum is primed to take on Durant. Kyrie and Kemba is a wash, and Smart vs Harden is also a great matchup.
As far as the rest of the team goes, despite missing Jaylen, we have more upside with Rob Williams, Fournier, Nesmith, Pritchard, Langford and Kornet , but the Nets have much more experience. I think Kornet will get some key minutes in this series.
