Leonard looked amazing against us in the Miami game. He would not be a bad pickup at all.
I think the Jazz are waiting to see what happens with Aron Baynes. The Suns almost bought him out before the season started so that he could go to a contender (and team of his choosing). If they don't make the playoffs (currently the 10th seed), there is a likelihood that they let him go to a team of his choosing (he's 33 years old). He's also a Spurs guy, and an Aussie. I can see him picking Utah, given the choice. That would potentially leave the Jazz to trade Davis and Bradley for another piece that they may need, or they could keep Bradley as the 3rd center (soon to be 2nd) and just trade Davis for someone who brings more shooting.
The Spurs are currently the 8th seed, and there are rumors that they might look to blow up their roster in order to gain in the draft. They are okay, but their two best players are 30 and 34 years old. If the Spurs look to blow it up, Dennis Lindsey is still well thought of there and has many friends and that's as often as not, the way NBA deals are made.
Davis for Marco Bellinelli works salary-wise, and the Jazz could always use more shooting.
Jakob Poetl's salary also works in a straight across trade for Davis, if Utah wants to keep 3 centers, and with Baynes being 33 yo, it might not be a bad idea.
At any rate, the trade deadline is always fun.
