After last night I'm convinced:
Teague
Smart
Brown
Tatum
Theis
You need to surround Brown and Tatum with shooters so they make the defense pay for doubles and crowding the paint on drives. Last nights' experimental lineup with Javonte did not work because he's a slasher and not a spot up shooter. So, the offense got stagnant and Brown and Tatum forced the issue. Ugly offense.
Given that Payton Pritchard showed he deserves some backup PG minutes, IMO, you can afford to start Teague and Smart at the same time.
