I think Kyrie has seen how Danny operates. My guess is he's simply holding Danny's feet to the fire and making him make the move for Davis before he commits to Boston. I realize some people think Kyrie could just make this easier by committing right now, but Kyrie also probably is clever enough to know Danny would likely just take having Kyrie locked up for granted and not try hard enough to get Davis.
I think the fact the rumors are that Danny wants to trade for Davis anyway just substantiates that theory. Danny probably knows exactly what buttons Kyrie is trying to push and will eventually get it done. Sure, he'll try at first to get Davis on the cheap, and won't give up any more than he has to, but I trust that eventually he'll come to his senses and offer what New Orleans really wants most (Tatum).
