I think there are a number of teams in the top 10 that want veteran starters to help them begin to make a push in the playoffs - Spurs, Sixers, and Rockets are the obvious ones, but the Hornets, Pelicans, and Raptors are there as well, each having key pieces that they think are Franchise players.
There's a possibility that one of those teams trades for Jrue or White with their pick.
The point guard thing is interesting though. That's the one position that I thought we were doing well with. White is a starting-level point guard. Tatum, when he comes back, is our functional point guard. Pritchard is the best bench point guard in the NBA (and better than probably 10 starters). Jrue can run point guard as well. Plus, the Cs did give Davison a contract that through next season as well.
It may be that they really like a specific player, or its a smoke screen, or they are planning on a roster overhaul.
