WALTHAM — You can tell just by the media crush at the Celtics  training facility 12 miles west of Boston on Route 128 that there is a big series about to begin involving the Celtics and the Cleveland Cavaliers .
The quotes from the participants provide another good clue.
The two teams, as any basketball fan will recall, met in an epic seven-game series in the 2008 playoffs. The series wasn’t decided until the final 30 seconds of Game 7 at the Garden when Paul Pierce  and the Celtics outlasted LeBron James  and the Cavs.
Before that series, fans and experts hoped for a great series. This time, it’s almost expected. But that’s about where the comparisons end as far as the Celtics are concerned.
‘Two years ago was two years ago,” Pierce said. “They have new players, we have new players. This is a whole new team. This is a different type of team. They’ve got a lot of the same players, we have a lot of the same players but it’s just like you grow up. Things change, you become better. You can’t go off what you did in the past. There’s nothing to that last series.’
Kevin Garnett  agreed.
‘They have better players,” Garnett said. “They have Shaq, they have guys that have been there. They have experienced players who were there two years ago. Delonte [West ] is better. [Antawn] Jamison  is there, has been through the grind. They have better players, more experienced people.’
When the Celtics open their Eastern Conference semifinal series against the Cavaliers on Saturday night in Cleveland, it will be the first time in the era of the new ‘Big 3′ they’re opening a playoff series on the road. It will also mark the second time in three seasons the two teams are meeting in the second round.
But whether opening at home or on the road – as will be the case this year – Ray Allen  doesn’t believe Boston’s series triumph in 2008 will have much of an impact this time around.
‘I don’t really think it makes a difference,” Allen said following Thursday’s practice. “That was yesterday. Now we’re trying to do this all over again. I’m sure that they remember. Playoffs in their building is tough and we remember Game 7 [in Boston] very vividly but it’s a new series. Even if we did play them last year, it wouldn’t have made a difference then, either. They’re geared up against trying to get past us going to the conference finals. The ground has to give one way or another and we look forward to taking more ground.’
The Celtics were also asked to make another comparison – Miami’s Dwyane Wade  and Cleveland’s James – and how beating the former might help them with the latter this series.
‘They’re not close at all, truthfully,” Pierce said. “They have better supporting players. LeBron is playing two or three other guys who have been in the All-Star Game. I can’t say that about Wade. The only similarity is they have one of the top scorers in the league. That’s it. You’re talking about two different players. They’re definitely focal points but other guys, you definitely have to worry about them. There are most consistent players in Cleveland and those guys can beat you also.’
‘LeBron’s a different beast,” added Garnett. “He’s obviously with a better cast than D-Wade. I think D-Wade is one of the best one-on-one players in our game. That’s true with LeBron but I think LeBron defers more to his teammates a little bit, with his supporting cast than D-Wade. He can turn around and he has 35, eight boards and nine assists. That means he’s all-around, not even mentioning the steals and blocks. He affects the game in so many different dimensions.’
