Good thoughts from Pez in yesterday's comments. My quick response: Although it would be nice to start a big player at Sg and finally not have the tiny backcourt, I'm fairly certain there is no chance that Salmons starts at the 2.
If he does start at SG the first three off the bench would be Kirk, BG and Noah (assuming Mad Bad Brad starts over him). That leaves no one (... Thabo?!) to spell Luol at the SF spot. Doesn't make sense to become that thin at SF and have 4 guards (Rose, Salmons, Kirk and BG) - when you could just have Salmons come off the bench and head up the second unit at SF. Salmons off the bench gives us much more lineup flexibility, as the first three would be Kirk, Salmons and Noah.
Not sure how this plays out long-term, but I don't think it makes sense to re-crowd the backcourt and intentionally create such a glaring weakness (no backup SF).
I do think Salmons starts at the 2 eventually (maybe next season), which makes BG expendable this offseason. Hopefully the Bull at least make him some kind of respectable offer without breaking the bank, because I will be sad to see the Bull' all-time leading 3PT shooter walk away.
