After a big shake up this weekend, a draft that seemed like a lock for the Celtics has developed into a big question mark.

News broke Friday that the Celtics and Philadelphia 76ers were in advanced talks about swapping picks in this year’s draft. These advanced talks transitioned into a finalized trade as of Monday June 19th. The assumption across the league is that  the Celtics would claim Washington PG Markelle Fultz with that number one overall pick. Now that that pick has gone to Philly, that certainty has all but dissipated.

Fultz has been touted as the only “lock” of this draft with regards to selection. The next several picks, specifically numbers two through 5 overall, could discernibly go to a number of players in any kind of order. With that in mind, let’s take a look at what options Ainge and the Celtics have at #3 on Draft Night.

Jayson Tatum, SF, Duke

In the days leading up to the finalization of this trade, Jayson Tatum has emerged as the clear favorite at #3 among analysts and fans alike. And for good reason. Tatum’s got a strong ability to score from anywhere on the floor. His Per 40 numbers translate to a very respectable 20.2 PPG and 8.8 RPG. Last year, the Celtics’ biggest area of concern came from a lack of rebounding. Tatum isn’t a rebounding phenom, but being able to contribute in that department is a big plus in his column.

I, personally, don’t love Tatum at #3. There’s a few things to highlight, but what I think is most important is that there’s not one thing he does astoundingly well. Markelle Fultz has been touted throughout the draft as a true scoring PG. Lonzo Ball’s biggest strength is his passing ability. For Josh Jackson, it’s his physical presence and raw explosiveness. Tatum lacks that one area that he excels in. And this doesn’t mean he falls into a “jack of all trades, master of none” category. When Tatum’s cold, he’s ice cold; he’ll throw up shot after shot with little success. His lack of defensive consistency is also a concern at the next level. With Avery Bradley and Marcus Smart potentially out the door after next season (something that I hope and pray does not happen), Tatum could sometimes be seen as a defensive liability.

I really think Tatum’s going to be a fine player. I just don’t think he’s the Celtics’ best option at #3. In the days leading up to the draft, NBA analysts have compared Tatum’s ceiling to Paul Pierce and Carmelo Anthony. I think as a comparison, these are spot-on for better or worse. All three of these players are great scorers anywhere on the court, and all three can contribute at a high level. However, these aren’t the kinds of players that can do it on their own. Pierce needed Kevin Garnett and Ray Allen to get over the hump and earn his first ring. Carmelo Anthony has been hit-or-miss since his days in Denver, always seemingly a few pieces away from being a truly great team.

Likewise, Jayson Tatum’s going to be a great scorer and a good overall player, but he’s not a franchise cornerstone. Tatum’s a good pick for Boston because he doesn’t have to be the star, he just has to score and crash the boards. If the Celtics are looking for a more well-rounded player at #3, I just don’t think Tatum’s their answer.

Jonathan Isaac – SF/PF, Florida State

The Celtics most likely will not take Jonathan Isaac unless something drastically changes in the 48 hours between me writing this and the draft Thursday. Danny Ainge hasn’t had Isaac in for a visit yet, nor have there been any rumblings of him coming any time time soon. Isaac, however, is my personal favorite for the Celtics at #3.

Isaac really is the ideal player for the Celtics in this draft. He’s a player that has fallen down draft boards in recent days for seemingly just a lack of face time. Not being a top-three player this draft and not coming from a big name school like Kentucky or Duke has hurt Isaac as guys like De’Aaron Fox and Jayson Tatum fly up draft boards. Despite this, he’s a player that could really make the Celtics a special team. Some of his biggest strengths come from his ability to crash the glass as well as defend. One of the biggest examples that jumps out at me comes from the Florida State-Duke games this year, when Isaac was tasked with guarding the aforementioned Jayson Tatum. In both games, Isaac was in Tatum’s shirt, causing him to cough up the ball 9 times over the two contests. Now imagine that kind of defensive ability matched with the likes of Bradley and Smart. It would be one of the best young defensive lineups in the league. Combine his defensive prowess with his ability to create shots and you’ve got yourself a bona fide NBA talent.

Even his current weaknesses are things that could be fixed. Two of DraftXpress’s biggest criticisms of Isaac are his lack of offensive polish and his wiry frame. Both of these issues are inherent in a 19-year-old. A young guy like Isaac has yet to really grow into his body fully, nor has he truly honed his skills as a player yet. Proper coaching coupled with NBA strength and conditioning could help build muscle mass and turn Isaac into a legitimate threat.

Josh Jackson – SG/SF, Kansas

After the news of the Lakers trading D’Angelo Russell to the Brooklyn Nets, it seems as though the rumors of Josh Jackson to LA are moot. With Fultz and Ball locked up, this leaves the door open for the Celtics to snatch up Jackson at 3. I love Jackson’s versatility as a player. He can do a little bit of everything offensively; he’s a great defender to boot.

While Tatum and Jackson’s games are often compared, the similar product is produced through two very different means. Tatum feels like more of a pure shooter. While I did comment on his inconsistency from the field, his abilities are undeniable. Jackson, however, is much more of a slasher. He can get up and down the court, and he’s certainly not afraid to drive to the basket for a score. He’s also got incredible vision to boot: while not exactly known as an assist machine at Kansas, On top of his playmaking ability, Jackson can reasonably guard four different positions on the court. This kind of versatility and adaptability is undoubtedly enticing.

However, his shooting ability is certainly lacking. He just really doesn’t have any semblance of a consistent shot. With a team like the Celtics that takes such a high volume of threes, it’s a bit of a question mark how Jackson would fit offensively. Would he be a weak link and screw up the pace of play by being unable to shoot? Or does he become the designated lane driver? Where he would provide offensively just isn’t as apparent as it is for Tatum and Isaac.

So there you have it. Who the Celtics could draft, who the Celtics should draft, and who the Celtics will draft. There are a few more possibilities on draft night, like the Celtics taking a chance on Dennis Smith Jr., or the Sixers taking Jackson and having Fultz fall into Ainge’s lap, but I’m honing my sights in on what seem to be the most sure things.

With trades being made, rumors flying around, and everyone in the NBA in a frenzy, I’ll try my best to keep the site up-to-date with the latest Celtics moves and rumors. And who knows? Between the draft Thursday and the news about apparent ties to Jimmy Butler, Kristaps Porzingis, and Anthony Davis, this team has the potential to look very different before the free agency period even begins on July 1st.
