Celtics co-owner Wyc Grousbeck checked in with the Dale & Holley show Thursday morning and talked about the Celtics' season. Said Grousbeck: "It has been up and down, we can't hide from that. You have to be honest with people and be honest with yourself. We've always felt, though, inside the team that this team has a chance, and that that was probably a lull in the middle of the season, not from being lazy, but from being tired or conserving energy. ... I think that's what's happened this year. I'm not trying to make make an excuse, that's just my honest opinion."
