I don't see McDermott as a guy who would be happy with two very unproven guys behind Taylor. If Taylor gets hurt, especially early in the year they would be in the same situation Marrone was in with starting Tuel, I don't see him as a guy who wants to look "unprepared". My guess is Peterman makes the team unless he is really awful and unless Jones makes remarkable progress Yates is the number 2.
Jones goes to the practice squad if he passes through waivers,
