Ball will play tons of minutes too, and Thomas and Ball would both be big enough to get minutes at the 3 spot as well. Plenty of minutes would be about what we expect from Nowell this year as the 3rd PG, 15-20 minutes a game depending on matchups.
And that's really all that top freshman top PGs get anyway. It's a tough position to crack as a freshman at P5 schools. Lewis is currently ranked 31, Jeremy Fears was 32 last year and played 15 minutes a game at Michigan State. Miro Little was 41 and played 7 minutes at Baylor. There's some exceptions like Jackson Shelstad at Oregon who played 32 minutes, but Oregon was also a bad team
