We'd be giving up too much on a gamble.
I would do one of the core and picks though, but honestly that is still a lot to move up just three spots. Think about how much ee had to give and sacrifice just to get kanter, burks, #5 pick, and #23 pick. Those were different deals, and missing the playoffs. To give it all up for incomplete players who have star potential is a huge risk. I think both Parker and Wiggins will be great, but there is still a chance Wiggins never learns to dribble, pass more efficiently, or shoot. And, there is a huge chance that Jabari is too slow to gaurd SF's, so then he'll be undersized against PF's.
I know it's not a popular idea, because he's been one of our better and more consistant players, but I would see if Favors and #5 moved the needle. MIL might bight because they'd get the rim protection they thought had in L. Sanders, which they apparently don't. Favors is athletic and can run the floor, giving his all on D, which is the kind of big man they want next to Giannis. They could also pick up another potential star at #5 like Vonleh, and be in a position to give him time to develop next to Giannis. There lineup could be:
PG - unknown
SG - unknown
SF - Giannis
PF - Favors
C - Vonleh
Those three pieces are all very long for their position (wingspan wise), and very athletic. All fuflfill a specific need for the team.
The Jazz would think about it, because it is only one core piece that they'd be giving up and a pick for a better pick. Our defense was best when Rudy was on the floor last year, and Favors' offensive game may never be adequate enough for the PF spot. If he has to play C, he is undersized. Last year, he played C, and as so his defense was a lot less effective then expected, because of size. Pairing him and Gobert in the frontcourt would be monsterous defensively, but would be a nightmare for the whole team offensively because neither can step out of the paint as a threat. Favors and Kanter might not work if Favors is forced to play the C to get the players that blow by Kanter. Gobert could easily develop into a monsterous shot blocking, rebounding and lob catching machine. His per 36 last year was 8.6 pts, 3.4 blks, and 13 REB. Pretty damn good for a rookie. If Favors is a center, Rudy might be our center of the future, as Favors per 36 only posted 16 pts, 10.4 reb, and 1.4 blks while manning the position. Those are still good #'s from basic stats, but certainly wasn't the shot blocker most expected him to be in his 4th year. A frontcourt of Kanter and Gobert has the potential to work well on both ends of the floor, because other teams are scared to drive when Gobert is close to the rim, and Kanter has the ability to step out on offense and stretch the floor. Furthermore, gobert and Kanter (at PF) are uncredible mismatches at their position. If Gobert is gaurding the rim, Kanter just needs to learn adequate positional D, which is something he can do.
