A couple things that could be responsible for this which would not be an indictment on either Ulis nor Bowen:
1) Perkins likely has professional aspirations, and would be slightly undersized as a SG in the League. If he can develop PG-level ball skills, it’ll do a lot for his chances at the next level (in my opinion)
2) It could mean that Josh Dix is the real deal and in line to play substantial minutes this year, which would be in-line with some of Fran’s preseason ravings on him. If Dix is as good as advertised, Perkins at the 1 and Dix at the 2 could be a lethal offensive backcourt where Ulis and Bowen (may be) more limited scorers
Just a couple of ideas. I’m sure that Fran will do a lot of tinkering throughout noncon as usual though to see what sticks
