There are a lot of teams with players that can play PGs. Its probably the deepest position in the league. Just looking at all the other teams you didn't mention in the East.
Nets-Harden, Irving, Mills, Carter
Knicks- Kemba, Rose, Quickley
76ers- Simmons, Curry, Maxey, Milton
Bucks- Holiday, Hill, Divincenzo
Magic- Fultz*, Cole, Suggs, MCW, Hampton
Hornets- Ball, Rozier, Martin
Raptors- Vleet, Dragic, Flynn
Pacers- Brogdon, McConnell, Levert, Duarte
Cavs- Garland, Sexton, Rubio
Heat- Lowry, Herro, Oli, Butler
Pistons- Hayes, Cade, Lee
Hawks-Young, Wright, Lou, Mays, Cooper
Wizards- Din, Holiday, Beal
That's just East teams.
EDIT- I'd put C's in the middle of the East right now.
