I haven't seen any of these players (including Grimes).
Just passing on info. Obviously I hope the Knix made a good choice and got a good player. Minor worry they outsmarted themselves with their wheeling and dealing and could have just drafted at their set slots and gotten 2 nice players. We'll see.
With the Knix talent level and middle of the road prospects, you hope you can find one starter among two picks in the early/mid 20's. More likely you get a contributing role player such as Quix. But there are always a few future starters out there from 20-40, and you hope to find them. I usually prefer drafting for fit, but this year I would have gone solely on talent/BPA. If either Cam or Jalen projects as a starter, I want in.
Jalen Johnson was from most accounts a lottery talent who had character questions for how he left his college team (and HS as well?). That motivation/maturity risk is why he dropped. ATL has a deep team and could take a flyer on a risk/reward prospect. Knix could have done the same given 2 picks in the 20's.
As some remarked here, Bones Hyground sounds rather duplicative of Quickly.
As for RJB, I think he's a pretty flexible cat. Can play at either wing slot on both ends. And do agree that his defense took leaps last season. He was our key switch and close out wing, having to make instant read and react decisions.
Compare to when Burks was in the same role on the 2nd unit and would drift too far away from his man, get buried by screens he didn't see forming, hesitate or make the wrong closeout read. RJB is a solid man defender but a very good off ball defender -- was quite nice as a switch/help/closeout team defender. As a hard worker, RJ should be able to up his on ball D more. Has a bit of trouble with quick first step bursts, and likes to be physical which gets him into foul trouble at times. But nicely competitive. While his steal rate might be somewhat low, likely due to mostly playing off-ball help D, it seemed he got a fair amount of deflections (as does Quix). Not sure if anyone has deflection stats available, and for RJB the help role will damp that down some as well.
