Seeing that Fox wants out of Sac-Town, this could be a part of his trade.
Minnesota: The Timberwolves have fallen into mediocrity this season, after trading KAT in the offseason. One of the minor reasons for this is the decline of the Point Guards of the Timberwolves. Mike Conley is only averaging 8 ppg and 4.3 apg. While they do have Dillingham, he isn't quite ready to be the Point Guard of a contender yet. Fox is perfect in my opinion for their offence, playing fast paced ball like Anthony Edwards. He is currently averaging 25.2 ppg and 6.2 apg.
Sac-Town: Fox clearly wants out of Sacramento and isn't willing to compromise on staying there. With him wanting to contend now, Minnesota should be a place he is willing to go to. While at the moment they aren't at the top of the west like last season, that is because of the changes they made over the offseason not working.
PS: This is my opinion and shouldn't be taken like facts. Also they should give the Kings some pick, but I am unsure of the amount.
