So I was comparing the likely offers the Jazz and Pistons could put together for Mike Conley since they seem to be the most likely suitors. I feel like the Pistons are probably more likely to get a trade done for Conley.
The Jazz could do
Rubio, Favors and a first. I think that is possible if DL feels a move is absolutely necessary for the Jazz. But it's not a guarantee DL would do that. And I'm not sure the Grizzlies accept this because all they receive is cap relief and a late first.
Rubio, Exum, Sefolosha and a first and/or young prospect like Allen or Bradley. The Jazz are reportedly against offering Exum. So I don't think that this happens. It may be our most intriguing offer for Grizzlies though, and it still might not be enough in their eyes.
The Pistons could do
Reggie Jackson (2 year contract), Jon Leuer (2 year contract), Luke Kennard (young lottery pick) and a first that will probably be top 20. The Pistons might even be inclined to add additional picks. I think the Grizzlies will probably see that as better than anything the Jazz can offer. Sure, they have to ride out the contracts of Jackson and Leuer next season before they get the cap space but it doesn't matter because they'll suck next season either way. They still get the cap space its just a year later, plus they get the young player and pick(s) they want.
Ultimately I think that the Pistons are probably far more desperate than the Jazz are in this situation. So I think the Pistons are more likely to get it done.
