In a lot of ways I would consider a move to get Bobby a vote FOR Ronnie Price.
If the goal is to contend, and the Maloofs seem to think it is, there is just no way to enter next season with an undrafted small college OG with 150 total NBA minutes under his belt as the primary backup to your star PG. But if you bring in an older guy like Bobby knowing that he will only be able to give you 2 or 3 years, you are opening up a mentoring situation for Price to eventually take over the job if he proves himself.
If instead you sign a James or a Claxton, the job is simply theirs for as long as they want it, and Price is just the 12th man filling out the roster.
