My guess is Rubio will be in the starting lineup for Friday, and Ridinour will be shuffled over to the 2 guard. He will be undersized there, but he is a decent enough shooter and is a solid defender so he should be able to succeed there. Darko is going to start for the time being, and I am fine with it. After all, he only plays about 15-20 minutes a game, and its not about who starts, its who finishes.
So the lineup will look like this, at least until Beasly comes back:
PG: Rubio
SG: Ridinour
SF: Wes
PF: That Love Guy
C: Darko
