He already has one. Wiggins literally had 3 go to moves in Kansas. Drive then a spin move, dribble pull up from mid and pulling up from NBA range 3. His real problems are his ball handling and finishing at the rim, and as he continues to improve those aspects of his game he'll become much more complete. His jumper was great in college, you could depend on him to hit 2 or 3 threes a game, but he was overall lackluster at the rim and creating his own shot.
Defensively is where he'll eat in his first year, he has a very unique body where even though he plays SG at average SF height, he has the longevity and explosiveness of a PF. He can become a defensive stopper at the NBA level, and it wouldn't be surprising if he racks up plenty of steals and blocks because of that longevity. Two-way players who are versatile are the future of this league, we saw it with Kawhi, PG24 and LeBron, so I think Wiggins will continue that trend. That said, his offense will take quite a few years to get where it needs to be, he won't be ROTY or anything.
Best point so far in this thread. I always say Wiggins barley knows how to play basketball. That's probably why he looks so "robotic" like everyone says. He lacks feeling and body control of all the greats he's been compared to. He's just learing an offensive game seems like, and doesn't know yet the type of scorer he'll be, but everyones expecting him to be the next Kobe, T-Mac, and even MJ
Like the post above said, Wiggins had like 3 moves in Kansas that he used often and pretty much worked:
the one dribble step back mid range.
the spin move in the lane
the pull up NBA range 3 pointer (when he was hot)
everything else was based off open court transition, cuts to the rim, rebounds, hustle points, etc where Wiggins doesn't need ot dribble much or think. Thats where he's best because he's just a freak athlete.
But right now it just seems like he's learing how to dribble and forming some go-to offensive moves that look like he's been watching too many JAMES HARDEN videos

. Yea some moves look good in a workout video but these same moves probably wont work right away in a real NBA game. That turn around jumper is pretty weak.
I'd be surprised if Wiggins comes out scoring 20+, knocking down jumpers, taking players off the dribble and breaking ankles but he'll be there in a few years with hard work and the right coaching. The problem is, after he goes #1 everyone will expect him to be the next Kobe, Lebron, etc....
