So aside from all the Kyrie Irving talk, there’s actually one other interesting Celtics storyline — who will be the 15th man? Sure, it’s not exactly a glorified position to have, but a position nonetheless.

There have been whispers of several possible suitors for the spot, yet nothing has really materialized. This gives us, the Celtics faithful, the ability to fantasize about our team getting any player on the market.

It’s always a possibility that the team could ride with 14 players, but where’s the fun in that? Personally, I love me some good ole fashioned speculating.

So, here’s some quick speculating on my take of the 8 best free agents for the Celtics.

I know you’re thinking, “He’s washed up”, but I think he would be a valuable guy at the end of the bench. If you look into his advanced stats this past season, Hibbert was actually a juggernaut on the defensive side of the ball.

In 2016-17 he posted a career best 5.1 defensive plus/minus and an astounding 6.5 blocks per 36 minutes. Last time I checked the Celtics needed a rim protector — here’s your huckleberry.

Dunleavy is an experienced player who can contribute in a limited role. It doesn’t seem like much, but it’s something. I mean, the Celtics are thin on veterans, so a player like Dunleavy could be very useful.

He’s by no means the 07-08′ Dunleavy who averaged 19.1 points per game, but he can still lace a few three’s. Just last year he shot a career best 42.9% from three-point land (better than the 42.4% he shot in 07-08′ season).

Dunleavy would be a good veteran contributor the Celtics should target.

Humphries is like the other guys on this list. He does one thing well, and the rest is overlooked. That one thing, is rebounding.

Humphries actually posted a double-double with his per 36 minutes stats (13.4 points and 10.8 rebounds). On his career, Humphries has never averaged less than 8 rebounds for his per 36 minutes stats. Just two years ago, he actually posted his career best in that statistic at 15.6 per game.

In a limited role, Humphries could finally give the Celtics a strong rebounding presence.

I’m just going on a limb here — I think Boris Diaw would be good on the Celtics. He’s a big man who has decent range and can pass.

There should be an emphasize on the passing too because man, he can really pass. Just this past season his assist percentage was 20.3. Al Horford, who is known for his passing, had a percentage of 24.4. Imagine the type of ball movement in the low-post with a lineup of Horford and Diaw.

I believe Diaw would fit beautifully with the Celtics.

P.S. I did see the video of Daniel Theis dunking on Diaw and I still am on board for signing him. Also, I’m really excited about Theis. Here’s the video if you didn’t see it.

The guy knows the system. That’s about the biggest reason he’s on this list. Well, I guess that’s not it.

At 31 years of age, Green is still ultra-athletic. The dude can jump right out of the gym if he feels like it. On top of that, he can score in bunches. In the Celtics Game 4 victory against the Bulls, Green sparked the team with 18 total points. He even went on to score double-digits in 3 other playoff games this past season.

Green would be able to give the Celtics a scoring punch from deep within their bench.

It would be great having Tony Allen back in Boston. Avery Bradley served great — if not better — as Allen’s replacement, but I would still love having him back.

Allen has always been a great on-ball defender as evidence by his 6 All-Defensive Team selections. Even as he’s getting older he can still take on a team’s #1 scorer. Now with Bradley gone, the Celtics could use that.

Allen even had a good year in other facets of the game as well. He posted the 3rd highest scoring season of his career (9.1) and his highest rebounding numbers ever (5.5).

The addition of Allen’s defense could be very useful when the Celtics run into an angry, 5’9 giant during the playoffs.

Thomas Robinson’s per 36 minutes stats are absurd. On his career, Robinson has averaged 13.1 PPG, 12.9 RPG, while shooting 53.6% from the field.

Can you guess his career average for minutes per game? It’s 13.4. That’s it. Could you imagine what he would do if he was given just 20 minutes a game? Sheesh.

The most attractive feature of Robinson’s is his age. At just 26, Robinson is oozing with untapped potential. Lucky for him, the Celtics have the perfect guy to let all that talent out. With the help of Stevens, I wouldn’t be surprised if Robinson was a league leader in rebounds.

The risk/reward seems far too enticing to pass up if you’re the Celtics.

I feel like whenever you have a chance to sign a former All-NBA Team member to a league minimum, you should.

Bogut was extremely productive in his limited role with the Dallas Mavericks last season. He was an efficient rebounder at 13.5 per 36 minutes with a 21.7 rebound percentage. Bogut was also a great defender last season as evidence by his 5.3 defensive plus/minus. He flashed his rim protecting ability with his 3.9 block percentage and 1 block per game.

Bogut would be able to help the Celtics on three levels of need: rim protection, rebounding and veteran leadership. That’s more than any other player which is why he gets the top spot.

So, how did I do? Did I miss any available free agents you would like to see in green and white next season?
