I have a feeling Danny really likes Doug McDermott. Not based on anything just a hunch. I thing it is possible to trade down and still get him. I know no one will agree with me but a have a feeling that Danny is very interest in Doug McDermott. I'm a celtics fan since the 70s and have seen a lot of Danny Ainge and this just seems like someone he would really want. Just my guess.
From what I hear, McDermott's eyes light up when people ask him about the Celtics. There's isn't much to dislike about him or his game either, especially now that he surprisingly showed above-NBA average athleticism at the combine. He might not be an elite 1 on 1 defender, but his team defense is excellent and his motor is high.
That being said, there's no way Danny takes him at #6. His floor is probably higher than almost anyone in the draft, but his ceiling is definitely lower than all of the other top-8 prospects.
The only way McDermott becomes a Celtic is through trade up or down and I don't think he's the kind of player you trade down for at this stage in a rebuild. As much as Ainge says that he sees this draft as a bunch of role players and McDermott appears to be destined for a career as a knock down shooter/high character guy on a contending team, I don't think anyone here would argue that both Saric and Smart have the potential to be go-to guys (though we could debate the likelihood of them reaching their ceilings all we want). Danny has shown a willingness to move up in the teen picks to get his guy (Olynyk last year), so I would not be remotely surprised if Danny did so for a guy like McDermott. This all depends of course on where McDermott is on Danny's board and whether or not the right deal presented itself.
The Celtics probably intend to draft best available with both picks and see what develops over the next few years. That could mean a high risk/reward pick like LaVine at #17(though LaVine is very far from an NBA level and his style of play makes me question his fit on a Stevens team). It could also mean that the Celtics want a reliable guy like McDermott that will make them better instantly while almost guaranteed to being a solid long-term contributor.
That being said, you might not want to draft two guys at the same position as it would slow each guy's development. In that sense, I can't see Danny trading up for Doug if Saric is taken at #6 or through a slight trade down. Smart at #6 would make a trade up for Doug seem like a perfect move as their skills would compliment one another (Doug being another high BB IQ forward that can stretch the floor and allow the team to play inside out with their bigs).
Rondo/Smart
Bradley/Smart
Green/McDermott
Sully/KO
KO/TBD Rim Protector
Offensively, I like the lineup of:
Rondo
Smart
McDermott
Sully
KO
Still no rim protection, but that is an elite rebounding and passing team with mismatches galore and crazy tenacity in the backcourt.
