The Boston Celtics hold the No. 27 and No. 40 picks in the upcoming NBA Draft (June 23-24), and on Friday, we heard that the Celtics are working out three players in advance of the draft: Zuby Ejiofor from St. John's, Andrej Stojakovic of Illinois and Kashie Natt of Sam Houston State.

Over the next three days, we will chronicle each player and how they may - or may not - fit with the Celtics, who went 56-26 this season and earned the No. 2 seed in the Eastern Conference playoffs.

After being eliminated by the Philadelphia 76ers in the first round, the Celtics have some questions to answer, but they also have a championship window that is still open that needs to be taken advantage of.

So, let's dive in:

A four-year college player from Texas, Ejiofor started his career at Kansas before playing at St. John's. Part of the program's turnaround under Rick Pitino, he became the Big East Player of the Year while also earning the Big East Tournament MVP this season. He was a two-time All-Big East selection and a two-time All-Big East tournament pick.

He averaged 14.7 ppg as a junior and 16.3 ppg as a senior as the Red Storm won the Big East regular season and tournament titles this year.

A physical player, he averaged 7.3 rebounds and 2.1 blocks per contest. He stands at 6'9.

At 6'9, Ejiofor is just slightly bigger than Jayson Tatum (6'8) and Jaylen Brown (6'6), meaning he doesn't occupy the exact same position on the floor as they do.

If Joe Mazzulla wants to go a little smaller with his lineup, he could use Ejiofor at the power forward position while still having both of them on the court together.

Furthermore, Brad Stevens has a stated goal of getting the Celtics better on the interior, and Ejiofor fits that bill. He shot 58 percent on two-point attempts in his senior year, and he also shot 72 percent at the foul line, proving he can be rewarded for his efforts at the rim.

His rebounding and blocked shot abilities are also a positive for a Boston team that lacked physicality at times, and they come with a high motor that should translate to the next level.

While maybe Stevens wants to get away from a three-point dominant team, the fact remains: Three-point shooting is important. Ejiofor attempted only 59 three's this past season, an average of less than two a game. He was 30.5 percent on those attempts (18-of-59).

Is he quick enough and skilled enough on the perimeter to be an offensive weapon in the modern NBA? Is he too small to be a true difference maker on the interior, both offensively and defensively?

These are the things that the Celtics will have to evaluate moving forward.
