I actually think they would start Thompson at SG. Much better shooter than Stauskas and thus a better fit.
PG - Dunn, Marshall, McConnell
SG - Thompson, Stauskas
SF - Covington, Grant
PF - Simmons, Saric, Landry
C - Noel, Embiid
DLeague - 24, 27, Holmes
That is with no free agent signings, which I don't expect. I would expect Marshall and McConnell to be the first two gone for free agent signings and Saric is far from a given coming over. I do think that one of 24 or 27 (or maybe both) will be draft and stash players, which also opens up a spot.
They still have a logjam at PF/C, but it is better in that scenario. But just think how bright the future would look if they signed someone like DeRozan.
