Nothing is meant to be perfect in Summer League.
The teams are thrown together last second and there is a lot of inexperience on the floor. Nobody is expecting the cleanest of games.
What they are expecting is effort. That can make up for a lot of mistakes and certainly stands out for players who are trying to get noticed and make a roster. That is the baseline of everything.
There might be talent gaps at times — especially going up against some younger teams that bring with them a lot of main roster players — but effort makes up that gap.
