Probably not. There will be players who step in just like has always happened and the US will continue to kick everyone's butt. We have some really good US players who could have provided some different but very effective skills, such as Loyd, Sims, Jefferson, Sloot, Ogwumike, Howard, Mitchell, McBride, Alexis Jones, etc. We will still have the greatest collection of players in the world, by far. EDD, Charles, Griner, Stewart and probably Fowles will still be available in the middle. Oh yeah, and we will still have Maya Moore.
The starters might have to play a little longer but who is going to beat a team with a starting five of Charles, BG, Moore, Whalen and Loyd? That is my prediction for the starting 5 in 2020.
I just wish a young guard or two had been added to the 2016 team to get some Olympic experience.
