Jimmy exacerbates the issues with Wiggins game. Jimmy hasn't made him a worse player tho. The fact is Wiggins doesnt add value on the court unless he's operating as a volume shooter. He's still a bad defensive player as well.
Eye test? Or stats?
Stats don't support calling Wiggins a "chucker" (15.9 fga/g) unless you claim the same about Ingram (13.1 fga/g)...which you don't. Jimmy HAS affected his FGAs (19.1 to 15.9) and FTAs (6.6 to 3.9). Jimmy is also a high usage player...that affects a player whose strength is scoring. Not sure why you keep implying that's not a good thing.
You want to paint Wiggins a certain way because that's how you see him. Check the stats. They don't support your opinion.
