Teddy Bridgewater
While the Saints didn’t miss a beat last year going 5-0 with Bridgewater under center, his ceiling as a quarterback remains something of an unknown. The 27-year-old has 34 starts across five seasons, and he missed the entire 2016 campaign with a devastating knee injury. His per-16-game numbers in his five starts last season were impressive: 69.7 percent completion rate, 3,856 yards, 29 touchdowns and six interceptions. Those would be impressive numbers that represent a step up from Garoppolo, but experience is an even bigger question mark for Bridgewater than it is for the 49ers’ quarterback. If San Francisco did pursue Bridgewater, it’s hard to imagine he’d provide a significant upgrade.
