Honestly, that is not a good team yet, so you are going to struggle quite a bit. You could maybe give Medved some more distro, but in a small sample size he hasn't been great either AND he is a freshman with a low IQ, so I don't know if he would help your struggles too much.
I would honestly just get your young guys a lot of minutes and start taking those baby steps...
Sorry if this sounds harsh, but I just don't think there is a "fix" to the team's offensive struggles.
