I think a lot of folks have conflated Brogdon's professionalism (he always says the right thing) with a desire to win and play the right way.
The reality is, he jumped from a contender in Milwaukee to Indiana where he could take more shots. After his year in Boston he sounds just as happy, if even happier, on a loser in Portland because “I’m valued here. Valued in this leadership/lead-guard role." In other words: as a starter who can shoot whenever he wants.
Brogdon always says the right things, sure, but when you look at the decisions he's made in his career, I don't believe he's as committed to winning as he claims. I don't miss him.
