NBA fans live a team’s ups and downs. They react to every draft pick, trade and free-agent signing. They debate the merits of the 15th man. They find significance in the most insignificant stats. They simply KNOW their team. So, too, do bloggers. That’s why we sought the opinion of the league’s best blogs — one for each of the 30 teams — to break down the team they cover and, of course, the Celtics.
We’ll finish the seven-part series with five forecasts from some of the best Boston Celtics  bloggers around (Don’t forget to check out Part 1 , Part 2 , Part 3 , Part 4 , Part 5  and Part 6 ) …

ON THE CELTICS: When you are six minutes away from an NBA championship, what do you do to make up those six minutes in the next year?
You try to get a little bit better. The Celtics are hoping that their gains are greater than their losses.
Is Kevin Garnett ‘s improved health enough to make up for the creeping age of this roster? Are Shaquille and Jermaine O’Neal  enough to make up for the loss of Kendrick Perkins  for half a season (at best)? Is Delonte West  enough of an offensive upgrade to make up for the loss of the surprisingly steady defense of Tony Allen ?
If the Celtics can stay a little bit healthier, maybe they can win a few more games to give them more home games in the playoffs. Maybe, just maybe, that will be the little edge they need to make up those six minutes and raise another banner.

ON THE CELTICS: With all the talk of what other teams have done this offseason, few people have paid a lot of attention to the fact that the Celtics — a team that was within four minutes of a title — addressed their two most pressing needs: Size and depth.
Now, the Boston Celtics boast what is probably the deepest team in the NBA.
Fast forward to the playoffs — since it would take the most catastrophic of events for this team to miss the playoffs — and the C’s will start their usual rotation of Rajon Rondo , Ray Allen , Paul Pierce , KG and Perk.
A team of those six guys would challenge for the last playoff spot in the East … and they’re backing up a starting five that, as Doc Rivers  loves to say, still hasn’t lost a playoff series.
The Celtics’ team chemistry has been remarkable. So, questions as to whether these guys can coexist are already answered.
They matched up well against most Eastern teams already, so the added size will only give the C’s more guys to throw at Dwight Howard .
The added depth will be able to keep up with Chicago or Atlanta. And the combined size and depth are the perfect counter to a heavily front-loaded Heat team.
Ultimately, this Celtics team has too much for the rest of the league. Even if a couple of guys get banged up, they have the depth to overcome it and properly rest guys for the playoffs.
Miami will be really good. The Celtics — with their experience, depth and size — will be just a little better, and they’ll get that 18th banner this year.

ON THE CELTICS: Before the preseason started, I predicted that the Celtics were destined to lose to Miami in the Eastern Conference Finals.
Dwyane Wade  and LeBron James  were tough enough by themselves. Once Pat Riley  paired them together and sprinkled a little Chris Bosh on top, they became the team to beat — regardless of who won the Eastern Conference last season.
Then the preseason happened, I got to see the Celtics play in real life rather than on paper, and I’m no longer convinced they’ll fall to the Heat (Yes, I realize it was just the preseason; bear with me).
I expected many of the older Celtics to digress this season. Instead, almost every Celtic looks better than last year.
Pierce entered camp in great shape; Garnett’s healthy; Delonte was a perfect fit; Marquis added confidence and perhaps an outside shot; Nate looks more comfortable after a full training camp; Davis has matured and potentially taken a leap; Rondo remained Rondo, only one year older and more experienced; Shaq has meshed far better than he ever did in Cleveland (I even saw him hedge a pick-and-roll last game); and Jermaine O’Neal’s addicted to the injured list.
Okay, maybe J.O.’s preseason didn’t work out perfectly, but every other player — stunningly — looks to be improved from last season.
A lot of teams claim to be motivated by tough losses, but the Celtics took that motivation to a next level. They used the devastation from the Game That Must Not Be Named and channeled it into returning in great shape, with only one purpose — winning an NBA title.
One through 12, the Celtics are the NBA’s most talented team. If healthy, they’ll win the East and then take down the Lakers in the NBA Finals . If healthy.

ON THE CELTICS: When asked by WEEI for a brief preview of the Boston Celtics 2010-11 season, the first thing I had to do was run to my desk and grab that fashionable pair of green goggles I’ve worn throughout my time as a Celtics fan.
Now that I took care of that, here’s what I think will go down this year for the hometown boys in green:
The Celtics are back and better than ever this season. After watching six preseason games, the amount of depth on this team cannot be compared to that of any other team in recent memory.
Von Wafer , a guy who had a solid tenure in Houston, was being talked about as a guy that could be cut from this team. That right there says something.
Of course, the team is going to undergo injuries and other hiccups throughout the course of the regular season that may draw some criticism, but if this Celtics team remains healthy come playoff time nobody (not even the Miami Heat ) can match their depth and playoff experience.
For that reason, I’m predicting a solid regular season record of 52-30, a healthy team going into the playoffs and … wait for it … wait for it … Banner 18.

ON THE CELTICS: Continuity. I’m a big believer in it as far as the NBA goes.
You take a look at the teams that have made the NBA Finals in the last 20 years, and the vast majority have been seasoned squads — units that have played together for years; players who know each other inside and out — their strengths and flaws, where they will be on the floor, where they like to catch the ball and everything in between.
You can’t buy that kind of knowledge in free agency, and it’s the biggest edge the Celtics’ core will have over their competition next year — one that will ultimately lead them to the NBA Finals.
The Miami Heat obviously have more talent, and they will get their championship(s) down the road, but next year will be a learning experience once the playoffs roll around. And they’ll fall short against the Celtics.
An improved offense, more depth and a deep sense of urgency will be enough to get Boston back to the promised land — where they will earn redemption against the Lakers after coming up empty last year.
