I know they are 2-2 in head to head games... I guess it will boil down to what happens in next few games and their respective conference records.
I do think a #6 seed would be huge - I'd rather the Suns play the Clippers in first round than the Spurs or Thunder. And if they do manage to somehow advance, I think the Suns would then avoid the Spurs in the second round, too.
Meanwhile, the Suns still have to make the playoffs...so all of this is conjecture and speculation.
