Summer League is always a tough thing to judge.
It is data and it is a public display of the team in a long offseason. It is hard not to get completely wrapped up in what we see.
On the other hand, Summer League is very much its own animal. It places a lot of players in roles they would not otherwise play during the season. Players are often working on their own things or trying to get seen and noticed not just for NBA teams but teams around the world.
What NBA teams are constantly trying to decipher is how everything will translate to the regular season and what they can use for their teams.
