If I am Milwaukee, I have no interest in Schroder.
I believe he'd be a bad fit on their team. Schroder reminds me of Bledsoe and the problems Bledsoe (dodgy) had next to Giannis (terrible shooter). Furthermore, Schroder already had big problems performing next to LeBron due to Schroder's inability to be effective without the ball and Giannis will require Schroder to play a good chunk off the ball as well.
You gotta have shooters next to Giannis. Not drivers / slashers / two point shooters. You gotta open up that paint for Giannis. And you gotta have guys who are comfortable off the ball. Not guys who are only effective on the ball.
