Many deals, big and small, have been reached at the NBA transaction market in the past three days. Some of them, like the one that turned Chris Paul into a bunch of future first-round draft picks, were remarkable work. However, some of them, though made by professional executives, did not seem so smart, or any good at all.

Does anyone have any idea what the Detroit Pistons are doing?

The Detroit Pistons worked with the Brooklyn Nets and the Los Angeles Clippers to make a deal that involved multiple players and picks. Simply speaking, Detroit gave LAC Luke Kennard and four future second-rounders in exchange for Landry Shamet.

It's hard to tell how much better Shamet is than Kennard or the other way around, but the difference is definitely not worth four draft picks.

Then Detroit gave a three-year, $25 million contract to Mason Plumlee and landed Jahlil Okafor. Plumlee is apparently over-paid and it's unclear why the team wanted Okafor. Perhaps their front office knew that Christian Wood will not stay. There are several teams chasing Wood with juicy deals after all. Detroit do not have a big market and understandably did not want to pay a role player too much money.

If that's the case, why did Detroit give Jerami Grant a three-year, $60 million contract?

As a 26-year-old, 2.06-meter-tall forward, Grant is a good defender – so is Wood – but he is not reliable in rebound protecting – Wood is – or a trustworthy shooter behind the 3-point line. Perhaps he can find a bigger role in Detroit but that's still not worth such a big deal.

What are New Orleans thinking extending Steven Adams' contract for?

When the New Orleans Pelicans acquired Steven Adams from the Oklahoma City Thunder, it seemed like a win-win deal. OKC removed a big contract they did not need in team rebuilding and New Orleans filled the empty position left by Derrick Favors with another big guy who only had one year left of his contract.

Then New Orleans extended Adams' deal by two years at $35 million.

It's true that Adams is a good finisher within the free throw line. He can also set quality screens, tussle for rebounding and not a defensive liability.

However, Ivica Zubac, Favors, Dwight Howard and Hassan Whiteside can do those things as well. Their salaries are: $7 million (Zubac), $10 million (Favors), $2.56 million (Howard) — Whiteside has not even found a job yet. Compared with them, Adams' salaries for the coming three years are $27.5 million, $17.5 million and $17.5 million.

One of the major reasons that a rookie contract of a talented young man like Zion Williamson is so valuable is that a player can contribute way more than what he's paid for. That's why many teams begin to build a squad around a young man from the second year he proves himself.

Well, it seems that Williamson will have to spend the next three years of his rookie deal sharing the limited floor under the rim with Adams. By the way, Eric Bledsoe also has three years left in his deal, which is worth $54 million — and he lacks shooting range too.

It's his own money Michael Jordan is burning, so…

New Orleans extending Adams' contract would have been the worst move during this year's off season, if it weren't for another mind-boggling decision of Michael Jordan, owner of the Charlotte Hornets, to give Gordon Hayward a four-year, $120 million deal.

Three years ago, when Hayward signed that four-year, $128 million contract with the Boston Celtics, he was 27 years old and just finished his last season in the Utah Jazz averaging 21.9 points, 5.4 rebounds, 3.5 assists and 1.0 steal, almost qualified for an All-Star spot.

Then in the following three years, he suffered a horrible ankle fracture, which hurt his athleticism badly; he also missed 111 regular-season games and 31 playoff games, and last but not least, he's 30 years old now.

Then Jordan decided to sign him for another four years with only $8 million less.

That's not even the only toxic part of this decision. In order to sign Hayward, Charlotte had to waive Nikolas Batum. As a result, the team will see a $9 million salary hole in each of the next three years. It put the Los Angeles Lakers in a great pain when they had to pay Luol Deng $25 million in five years, now Charlotte get to taste something similar.

By the way, both deals happened when Mitch Kupchak was the general manager.

We have talked enough about Jordan's confusing decisions running the team. At least someone should do something about his obsession of giving big contracts to point forwards – neither Batum or Hayward are Scottie Pippen.
