1. CB Casey Hayward
I know that many Charger fans are going to roll their eyes at Casey Hayward's inclusion on this list and rightfully so. Hayward was awful for the LA Chargers last season and it would not be surprising to see him regress even further in 2021 because of his age.
However, it is not a guarantee. While he played, Hayward was a bit banged up last season and was not at full health. While his prime days are definitely still behind him, there is a path in which he is better in 2021 with better help.
It has happened before with old cornerbacks. Old cornerbacks can regress very quickly but they can also rebound and surprise after a bad season. Darrell Revis was an All-Pro in 2011, was hurt in 2012, was not that great in 2013 then rebounded with a second prime starting in 2013.
Richard Sherman was poor in 2017 and 2018 and seemingly lost his Pro Bowl form and then had a breakout season again in 2019 at 31 years old, it is possible.
Personally, I do not think Hayward is going to be a cornerback who is well above-average but I would not be shocked if he plays that way against the Chargers. There is going to be an extra chip on his shoulder after being cut and the two best games of Hayward's season next year very well could be against the Bolts.
Simply put, don't completely sleep on Casey Hayward.
