Yeah, I find that interesting too. As strong as the consensus has been about the top 3 players, they don't really get a lot of franchise player anticipation. Even Jabari Smith's supporters admit he's probably going to have a Rashard Lewis type of career. The comparisons for Banchero are pretty mediocre in general -- he's a PF who need the ball in his hands to be effective. And then there's Holmgren whose best-case scenario is a stretch 4 with better defense. All of them are fine as prospects -- they all produced as Freshmen and have good size and some significant skills but they provided little to no tournament heroics, no eye-popping athletic feats, nor do they stand out statistically as eventual stars*. All of that is coming from "lesser" prospects this year. Which is weird.
*EDIT: Actually, I should revise that. Holmgren does stand out statistically. I'm really only concerned about him because of his position. Ruby Gobert is a 3x Defensive Player of the Year and his team lost in the first round to a Dallas squad that rated better than them defensively despite playing extreme small ball. The current state of the art defensively in the NBA is all focused on switching to defend picks around the 3pt line, not protecting the paint.
