I expect very little from Agbaji in summer league -- but i don't think it will mean much.
Players who require others to initiate their offense for them usually look terrible in summer league. Either:
a.) He will never get the ball, because Nembhard is either looking to score, or struggling overall. Then he ends up putting in like 2-5 stat lines, even if he is doing all the right things.
b.) He gets the ball, but out of rhythm or in the wrong place, and then ends up shooting a bad percentage.
c.) He gets frustrated and tries to initiate the offense, leading to turnovers because.... that's not his game.
Hopefully we see some steals and other flashy defensive plays, but good defense in the summer league is also hard to find.
