My son (small plug - he does a Locked On pod for the draft) said the Pistons glaring need was explosiveness and physicality (don't remember exactly how he phrased it). They went out and got Ivey (I'm not sold on him but his ceiling is REALLY HIGH) and Duren (really good value at #13). Detroit could be on the verge of a massive turnaround if Ivey hits.
OKC - this was my "other" team. I believe 100% in Chet, but after that foot injury? Who knows? Giddey has some flaws with the shooting I'm not sure can be fixed and I'm not as high on SGA as I once was. I really loved Jalen Williams (SCU) in Summer League. I also like Aaron Wiggins as a rotational player. Dieng is intriguing but a couple of years off. Tre Mann could be a breakout player this year and would change the trajectory of the team. Poku needs to find a role - this is his year 3. They are the model the Jazz are emulating right now - stockpile picks and take home run swings and you will be in good shape if 2 or 3 connect.
Houston - if I were still doing fantasy basketball, Sengun would be a late round sleeper pick. Sans Kevin Porter Jr, I think this team has the right pieces to grow into a contending team.
Orlando is a ways off. Biggest contracts are Jonathan Isaac, Fultz, Wendell Carter Jr, Gary Harris, Terrence Ross... so the timeline isn't right for them right now. They a couple of guys that haven't hit yet but still might: Suggs and RJ. The one guy I'm buying is Franz Wagner. That guy will be a key role player on a championship team one day. Don't know if that will be in Orlando though.
