Golden State - Steph Curry & Klay Thompson
Probably Houston - Russell Westbrook & James Harden - Not an ideal fit like GSW but a lot of individual talent and I believe their backcourt would be even better away from Mike D'Antoni.
Maybe Portland - Damian Lillard & CJ McCollum
Maybe Philly - Ben Simmons & Josh Richardson
... still thinking
Not ATL. Not BRK. Not CHA. Not CHI. Not CLE.
I would take Dallas - Luka Doncic and whoever (Seth Curry, D.Wright, Hardaway Jr)
Not DEN. Not DET.
Maybe Indiana - Victor Oladipo and Malcolm Brogdon.
Not counting LeBron as a guard otherwise the Lakers would be a pick. LeBron and whoever. Danny Green, he's their best guard.
Not MIA. Not MIL. Not MIN. Not MEM. Not NYK. Not ORL. Oklahoma is pretty strong (CP3, SGA) but doesn't make the cut. Not PHO (show me more, that they can maintain this). Not TOR.
Maybe Sacramento - Buddy Hield & De'Aron Fox - I love that duo. I especially love Hield's outside shot-making. Fox is a terrific talent. That one might be a probable and not a maybe.
Not SAS.
Maybe Utah - Donovan Mitchell & Mike Conley - but I don't think so. Not wild about Mitchell.
Not WAS.
----------------------------
So that leaves me where:
3 definite yes - Golden State, Dallas, Houston (actually, Houston is a definite, so I'll add them).
3 Maybes - Philly, Portland, Indiana
3 Honorable Mentions - Utah, Oklahoma City, Phoenix
Add LeBron's Lakers to the yes if he counts as a guard.
