CANTON -- The most optimistic day of the year for any NBA franchise tends to be media day. Everyone has a clean slate, is entering the year in the best shape, is willing to do whatever the team needs and can't wait to get started. Still, after listening to players and coaches over a good three-plus hours on Monday, there is still plenty to take away from the avalanche of interviews. Here are 10 things you need to know from Celtics media day:

1. Daniel Theis is completely healthy: The German big man had his meniscus repaired last spring and was working his way back throughout the summer months. Kyrie Irving and Gordon Hayward have been playing 5-on-5 for a couple of weeks now and Theis has joined them on that front, which puts the C’s rotation at full strength heading into the preseason.
