So total speculation here, but one way to read these reports that the Pistons have agreed to a Bagley trade, and that the trade will be finalized and announced by the deadline tomorrow (instead of right now) is that Detroit has agreed to take Bagley, but is debating between two Bagley deals.
It is possible that Detroit and Sacramento have tentatively agreed to a small Bagley deal, for some combination of Josh Jackson, Frank Jackson, Diallo, Lyles, etc…, BUT that Sacramento also has an offer on the table for Grant (perhaps Bagley, a first round pick, and matching salaries). It is then possible that Detroit is telling Sacramento, “yeah, we will take Bagley, but we want to see if we get a better Grant deal before we decide which Bagley package we will take.” I would imagine (if any of this is true) that Monte has told Detroit that you need to make a decision by x time tomorrow so that we can pivot to plan B.
That would also explain why we saw no movement on Holmes today. What you do with Holmes would depend on if you get Grant. If you get Grant and keep Barnes, you probably don’t trade Holmes for PJ- you either trade him for backcourt help or keep him as the backup big. If you don’t get Grant, you take the scraps you get for Bagley and then focus on trading Holmes for a wing (like PJ).
Maybe I am completely off base. Just a way to synthesize the reports that we supposedly have a Bagley deal, it won’t be finalized until tomorrow, and we heard nothing about Holmes today despite wanting to move him and having suitors.
