Is the best move to give experience to Costello now or to hope for a peaking 5th year Chryst next year? Would putting Costello in now give him needed experience, or is it risky and dangerous to put in a less experienced qb now given our current issues? Would we be sending Costello into a Luck-Colts type of situation?

I believe a significant number of Stanford fans, as well as the coaching staff, are now asking the exact same questions you pose.
To help answer those questions I think Costello needs a bit of playing time. The coaching staff has now seen Chryst play 8 or 9 games so they are aware of his strengths and weaknesses. Regarding Costello,  until he plays at least a couple of Quarters, the coaches will not really know what he may bring to the table.
