Where is this coming from? The Bucks were running a more pro style and structured offense than the Kings were.
In regards to Summer league being more like pickup games than real NBA games: mostly scrubs/rookies trying to make the league, rookie referees who are not very good, loosely officiated games, and many turnover-loaded out of control games.
Some people should just admit that they are haters. I bet even if Evans averages a 20 pts, 7 rebs, and 7 assist (just hypothetical here) this season, those people are still going to be hating because Evans didn't average 10 assist like the beloved Ricky Rubio would/could have. I get the feeling that Evans is going to have to average a triple doulbe, AND bring three championships to the Kings before those people stop hating, and even then it might not be enough.
