Casey Hayward - Cornerback - 2016
After a disappointing 2015 campaign for the Chargers, including being the 21st ranked defense in the league, there was a lot of change that needed to be done. Signing Casey Hayward after he had an impressive stint with the Green Bay Packers was something that could jump-start this defense.
In Hayward's first year with the Chargers, he became a pro bowler as well as the leader on that defense with seven interceptions, including one being returned for a touchdown. This is a signifcant improvement from a team that only had 11 interceptions in total the year prior.
In all of his years as a Charger, he was making plays and consistently making teammates around him better, which granted him a three-year contract extension in 2018 totaling $34 million. His abilities combined with an at the time developing Derwin James created a spark in the secondary that proved daunting to opposing offenses.
Hayward voiced how much he appreciated the Chargers for believing in his abilities, and he has shown the league that he is not just a nickle cornerback like everyone had him written off as. His impressive play while he was on the Chargers is what puts him in the top list of free agency signings by the LA Chargers.
