Jason Terry once again oozing confidence after the Celtics hosted an open practice Sunday at the Garden.

On Celtics-Heat rivalry: “I’ll never forget ’05-06 for me [when the Heat beat his Mavericks in Game 6 of the 2006 NBA finals]. I should be a two-time champion right now, but it wasn’t so. I’ll never forget that feeling, walking off that court in Game 6 in Dallas, when the confetti dropped on our head. I like to remember winning the championship, but what sticks in my mind more than anything is when we lost. I’ve gotta believe it’s a feeling similar to what Boston felt last year in Game 7, so I come right into the rivalry, I’m yearning for it and that’s game No. 1. Whether it was Miami or somebody else, it’s just basketball, it’s the season and it’s Game 1.”

On C’s title chances: “A lot of times when you see your team on paper before the season, you’re like, ‘OK, we might have a chance.’ But as we worked through the September month, which was earlier than usual, into training camp, the trip to Europe to our last practice today, we’re legit; we are for real. And I think to a man we are a very tough team. I think our bench is deep, but our starting lineup is a beast. These are champions. These are guys who know what they want, and the ultimate goal is to win a championship.”
