I have no doubt that Drummond would eat up a ton of boards for this team. He would be like a super charged Kanter who can pass and is more mobile defensively. On top of that he has a bit of vertical gravity that Kanter does not. Unfortunately I agree with many of the posters before me that I'm not sure he's worth 28 million. Also an issue is that he can opt out at the end of the year to explore the market and possibly get more (not sure he will.)
Let's assume that his cap hit is the same going forward, he would have to be one of our 3 most productive players on both sides of the ball for us to have a shot. The game is continuously trending towards players who are able to dynamically impact the game, and that isn't Drummond.
The argument is that we are in the same situation with Hayward, and while that's fair, would trading Hayward be worth the optics? We have just gotten over the league wide perception that free agents don't want to come here (regardless of the validity of that perception.) We also are giving up a swing of the bat in the back end of the lottery in a weak draft (that doesn't bother me as much.)
Long story short, I'm not sure Drummond is the dominant big man we want to hitch our horse to going forward.
Here's the thing, Hayward is damaged goods and he will most likely opt in next season at 34m.
That means the Celts' total salary will be closer to 140m.
If the Celts remove Hayward's contract, the Celts' total salary next season will be around 100m.
This is where swapping Hayward's contract for Drummond's contract helps the Celts.
Not only will it give us a chance to see how Drummond fits in with the Celts, it will also only cost the Celts around 29m next season if Drummond doesn't opt out.
Worst case scenario is Drummond doesn't fit in and he opts out.
That will put the Celts under the salary cap, which means the Celts will be able sign someone from the free-agent market.
I think gambling on Drummond for half a season and the playoffs is worth the risk.
Celts will never be able to sign Drummond as a free-agent if the Celts don't get him now.
The Celts will be able to address the need for a big man, in the summer of 2020, if the Celts have flexibility.
Celts will not have the cap flexibility if Hayward is still with the Celts next season.
The result will be having the same team this year for next year, plus the 2020 draft picks.
Not a good idea to wait until Hayward's contract is off the books, in 2021, to start building a championship team.
