When Vikings quarterback Teddy Bridgewater went down with a devastating leg injury last August, Minnesota was left with a 36-year-old backup in Shaun Hill who had a total of eight starts in his previous five seasons. Obviously, the Vikings were not planning to need Hill on the field at all during 2016, but injuries happen in the NFL and teams have to be prepared.
Minnesota most certainly was not prepared for any type of injury at the quarterback position last year. Hence the reasoning for making a desperation move to acquire a quarterback in Sam Bradford who has never won more than seven games in a season.
