I just love Brogdon's fit next to Booker. He's an incredibly efficient scorer at the point guard position. He shot 49% from the floor, 39% from the 3, and 88% from the free throw line. That's not far off from 50/40/90, and he's a really good defender.
I don't think he's an all-star, but that's not necessarily what you need or even want next to Booker and Ayton. You don't need a volume scorer; you need a high efficiency shooter who plays strong defense and makes good decisions.
Brogdon had a lot less hype after his ROY performance (granted, in a very down year for rookies), but he actually raised his ppg from 10 to 13 in his sophomore campaign.
What's nice is that the Suns should have good intel. I was watching highlights from the game where Brogdon scored 32 on 11-14 shooting against the Suns, and the broadcasters mentioned that the coach who worked with him daily during the season was...Joe Prunty.
