After what I saw in the Stanford game, so long as the play calling is straightened out, I am VERY impressed with Bennett. I would be very happy to see him as the starter.
I see three options here:
1. Select one QB intended to play the entire game (Bennett is the best choice).
2. Use a shuttle QB system (a la O'Hara-Dunniway)
3. Use the 1950s Rams system (Waterfield plays 1Q, Van Brocklin plays 2Q, and the "hot hand" plays the entire second half)
I'm not really a fan of the shuttle quarterback system, but we did make it work with O'Hara and Dunniway. It worked when I was at Delta (after I left UOP but before I got to Sac), but that was a weird situation where we ran a hybrid Run and Shoot-Wishbone system designed by former Tokay HS/LB State/Hamilton Tiger-Cats QB Todd Dillon that guaranteed that the defense was wrong because of timed shifts between the two formations, and we had a pair of quarterbacks suited to each, but close enough to be credible in both. SD and Sting are in a much better position than me to determine if Bennett and Conklin would be suited to the shuttle. I would actually use a fourth option, also something of a hybrid: Start Bennett, bring in Conklin for one series during the early second quarter so that Bennett could get a different viewpoint guided by the OC or QBs Coach, and then send Bennett back in.
That said, whether we use my hybrid idea or not, the single QB situation has historically been the best, and I believe Bennett is the best one we have at the moment.
