The Boston Celtics have had their Media Day and training camp early to facilitate their preseason exhibitions in Abu Dhabi later this week, but they have done so with a few notable shadows hanging over the storied ball club. The more imminent and tangible of those two shadows comes in the shape of Karl-Anthony Towns having been dealt from the Minnesota Timberwolves to the New York Knicks. The other of the two is more phantasmal and harder to pin down, simply due to the ephemeral and volatile nature of the moving pieces involved. That would be the pending sale of the team we just learned more about through a recent article from the Boston Globe's Adam Himmelsbach. Just how much are these twin specters making their presence known to the Celtics at training camp? To get to the bottom of this question, the hosts of the CLNS Media "Celtics Lab" podcast linked up with the "Garden Report" podcast host and Celtics beat writer Bobby Manning to get a feel about where these issues register among the players and coaching staff ahead of the start of their title defense. Both loom large in very different ways as potential barriers to Banner 19, but is it too early for either to impact the Celtics? The Celtics Lab podcast is brought to you by Prize Picks and Gametime.
