Can the Celtics do it this year?

I think the reason that they couldn't win last year was that their tallest player was Kevin Garnett, at 7 feet. Sure, if we were talking KG in 04 the Celtics would have easily been able to win. But this year, they had no other big men options when KG had to sit down. Now with the additions of Jermaine and Shaquille O'Neal, two older but still usable big men to cover for perkins and play for Garnett, they finally have some serious length. What do you think?
