MILWAUKEE – With four straight wins and nine in their last 10 games which now has the Boston Celtics (31-22) holding down the third-best record in the Eastern Conference, the Celtics are in no mood to celebrate.

“We’re playing some good basketball right now, real good,” Boston’s Amir Johnson told CSNNE.com. “But we can get better; we need to if we want to make sure we do all the things that we set out to do this season.”

That’s because their approach to their recent run of good fortune is similar to the outlook that most good teams have when things break their way.

Times are good, the wins are racking up but there’s plenty of room to improve.

Even after scoring a season-high in their 128-119 win over the Sacramento Kings on Sunday, you can rest assured the Celtics will remember that game more for the season-high turnovers (24) than points scored.

Some might interpret the Celtics as being a team that’s never going to be happy.

That’s not true.

They can do happy.

Being content?

That’s another story.

Success has been something this group just refuses to settle down with, because in their minds there’s always an area to get better at, a hurdle to overcome, a challenge still awaiting them.

And as they head into Tuesday’s game at Milwaukee, the Celtics must continue to show that they can handle success regardless of who lines up across from them and what that team’s record may be.

The Bucks, considered at the start of the season as a team that could potentially make the postseason as a relatively high seed, have been a disappointment on many levels this season - none more than their 20-32 record which includes their current streak of five straight losses.

The records indicate this should be an easy victory, something the Celtics know is just not the case.

While many will see Boston’s miraculous win at Cleveland as being a defining moment for this team this season, players tend to point to Sunday’s game against Sacramento as a more telling example of how far Boston has come this season.

There was no let-up against the Kings, the kind of thing you expect from a relatively young team that’s still learning how to handle success.

Beating Sacramento was a good step towards showing their maturity as a team which will be put to the test on Tuesday night against the Bucks.

Those non-elite teams near the bottom of the standings often provide the stiffest competition. They play more relaxed with a nothing-to-lose mentality which makes them an extremely dangerous foe.

But the Celtics are proving to not look ahead or past any opponent which is a good quality trait.

However, fans don’t need to subscribe to that line of thinking. They should see this team and their play for what it is, and that’s the best of Brad Stevens knowing that he and this group can be even better with time.

When you see one-fifth of the league’s head coaches at the start of the season no longer leading their respective teams, it makes one more appreciative of what Stevens and the Celtics have been able to do in a relatively short period of time.

They have dismantled this roster, rebuilt it and now find themselves among the tops teams in the East despite having a squad that’s among the youngest in the NBA.

And that doesn’t even take into account all of the draft picks and trade exceptions Danny Ainge has acquired along the way.

The future is extremely bright for Boston, whether Ainge decides to use those assets to acquire an established veteran or continues to build through a mix of the draft, free agency and timely trades.

And that Celtics fans, is worth celebrating!
