Boston Celtics fans will be the first to tell you that they have a great basketball team that could potentially win in the Eastern Conference. However, a huge question mark looms as to whether they should get an upgrade if they want to build a championship roster.

This is the question that has bugged a lot of Boston hoops fans over the season as they look at the situation in the Western Conference. The top teams there are top-heavy talents, and it would require smart business decisions from Danny Ainge if he wants to bring Beantown back to the NBA Finals.

As revealed by Jay King of The Athletic, the Celtics will have a rough time trying to find the right upgrade over:

Some rival executives believe the Celtics could have a tough time finding substantial upgrades on the trade market. Their salary-cap situation just isn’t conducive to a big deal. After their top five players (Kemba Walker, Jayson Tatum, Jaylen Brown, Gordon Hayward and Marcus Smart), the team’s next-biggest contract belongs to Daniel Theis at $5 million. That means the Celtics haven’t wasted money in the wrong places, but it also means they don’t have any bloated bench salaries to swing for a high-priced acquisition. Barring an unexpected decision to break up their core, they are limited in whom they can target.

Given this case, it will be difficult for the Celtics to acquire a disgruntled star who can immediately boost the team's chances. While Kevin Love is the most valuable asset they can chase for, they cannot hope to bring him over without letting go of one of their star players.

With this dilemma, Brad Stevens may be forced to try and find a way to win with his current crop of players. It may be a tough task to achieve in the current NBA landscape, but their situation gives them little to no chance of harmlessly upgrading their roster.
