Kyrie Irving on Stevens/Hayward bond: They have an unspoken language already

(Greg M. Cooper/USA TODAY Sports)

WALTHAM — The Celtics continued Day 4 of training camp back at their normal practice facility on Friday, but Brad Stevens was pleased by the time the group spent together in Newport, RI and where the team is from a health standpoint.

"Everybody’s been great, everybody’s healthy," Stevens said. "We’ll add in maintenance days for different guys as we go on. Kyrie will go very very light today. Then, ultimately, that’s just an individual thing. But everybody is — if we’re playing a game tomorrow, everybody is available and ready to go. We’re in good shape."

The bigger challenge now for most members of the roster is trying to quickly build chemistry on and off the floor with their new teammates and coaching staff. Even though Gordon Hayward is one of the 10 new players to Boston, Kyrie Irving is already impressed by the connection that he has with Stevens on the floor from their Butler days.
