Bruins coach Jim Mora maintains that Josh Rosen could start even if he misses an entire week of practice. If that scenario unfolds, the stellar QB would be one of the first college players ever to take the field under such circumstances. Backup Devon Modster was a big-time recruit, but he is a freshman who would confront a formidable pass defense. The Utes are less intimidating against the run, yet UCLA is a mild threat on the ground. For a home team on a four-game outright losing streak, there is no better medicine than going against a horrid rushing defense, worst in the country. The Bruins are not exactly road warriors, having succumbed in five straight ATS.
