Burke is fine. As was mentioned earlier, Raul's been playing against a similar level of competition to Summer League for the past two years. He also doesn't have the huge amount of pressure on him that Burke does being the #1 PG selected in the draft.
From the little research I've done, it seems like the vast majority of NBA starting point guards struggle in Summer League, particularly if they're at a disadvantage in terms of height. That isn't to say that they won't be successful - it just means that they have a huge growth trajectory to learn the system, adjust their games, and learn how to capitalize on both.
He's smart, hungry, and a hard worker. He'll be fine.
