No chance Utah agrees to this before the lottery. It'd have to wait until then.
They'd probably agree to it, they'd just put protections on the pick.
Which would totally defeat the purpose of getting the pick in the first place.
Because the Jazz will be more likely than not to improve when they get Rondo and Bradley, and the only shot you'll have of getting value for Rondo is by getting lucky on the lottery. If they protect the pick you lose your slim chance of making out in the trade.
The Jazz aren't improving much, if at all, this year by getting Bradley and Rondo. And the Jazz aren't trading us the 4th pick in the draft in this deal.... ever.
There's really no reason for the Jazz to do this before the deadline at all, especially considering the Cs are highly unlikely to trade a gimpy Rondo right now to begin with.
Next...
Bradley for Hayward is something of a wash. The odds of Rondo not significantly passing Burke's level of play this year in the near future are IMO pretty slim.
Avery wishes. As for Rondo.... shocker, Tim!
Here's a bballreference comparison of Hayward and Bradley so far this year. http://bkref.com/tiny/XN8P0 . Bradley's actually outscoring Hayward on a per minute basis and he's scoring almost as efficiently as Gordon. Factor in the difference in their defense and it's close to a wash.
FWIW, Bradley is outscoring Hayward per 36 by less than half a point while taking almost two more shots a game... and they're almost exactly the same for usage rate.
Also, Hayward has the edge in win shares, TS%, Free throw rate, and while his DRtg is two points "lower" than Bradley's, his ORtg is four points higher.
If it's a wash, it's a wash in favor of Hayward, all contracts remaining equal.
Either way, I'd still rather have Alec Burks.
