5 takeaways from Celtics practice and the Shamrock Foundation gala

(David Butler II-USA TODAY Sports)

With the start of the regular season just around the corner, it's been a relatively busy past 24 hours for the Celtics. The entire team was in attendance at the Shamrock Foundation Tip-Off Gala on Thursday night at the Westin Waterfront in Boston before getting back to work on Friday morning at the Auerbach Center in Brighton. Here is a closer look at a few items of note from both events.

1. Wyc Grousbeck is all-in on this season: The Celtics co-cowner spoke for the first time Thursday about Kyrie Irving's commitment to re-sign at the Celtics Shamrock Foundation Tip-Off Gala (an event where the organization raised over a million dollars to support children's charities all over New England).

"I thought that was super cool," Grousbeck said of Irving's announcement last week. "If I had known it was going to happen, I would have been there. I think it's just a stepping stone on the way to making a decision next summer. That's the way it all works, and I think he wants to focus on this season and have that distraction and sense out of the way. It's for him to say. But in terms of the relationship with Kyrie and the Celtics and his teammates, this bond between these guys -- I think -- is the real deal. I've seen 16 rosters now and this team is knit together. They're a real team and they're taking a great approach to this season. I'm really excited for the whole team, not just Kyrie."

When pressed about expectations heading into this season, Grousbeck was not shy about putting the pressure on this group.
