Early returns on Kyrie the superstar #1 scoring option on a contender ... not great.
Still, gotta give the group time to gel together. Especially since they're missing one of the key cogs of the offense they thought they were going to be running.
Look at the Bucks -- several of their key guys have played together for a 2-3 years now. The Celts are going to struggle in close games, not just because Kyrie won't be able to win games by himself, but because the team as a whole is not experienced at executing together.
