I don't care who they face.
If the Celtics cannot beat any of the possible teams they might face in any round, well then they simply weren't good enough, and therefor it doesn't matter.
You're either good enough to beat all comers, or you're not. This idea of wanting to avoid certain teams is a loser's mentality.
It doesn't matter. Every team presents a unique set of problems and the Celtics aren't sweeping anyone. They can beat any team on that list best-of-7 and lose to any team on that list if they start clanging their shots like they did during the 2 weeks leading up to the all star break.
