It doesn’t solve them at all. Dennis is far worse than Kopp offensively.
Kopp is a career 36% 3-point shooter, Dennis is a 34.4% career 3-point shooter, and was 36% career 3-point shooter before this year. Plus he's more versatile and vastly better at driving to the basket than Kopp. Dennis is the better offensive player, but is coming off a bad shooting year
