I was going over free agents and found someone who fits the Will McClay mold:
Michael Davis, CB, Chargers
You've never heard of him so Will McClay will think it's clever. Undrafted and then cut, he has Will McClay Arena league complex written all over him.
He's tall (6'2") so he automatically qualifies for the Seahawks CB preference that everyone is associating to Dan Quinn.
His PFF grade last year was 63.1. He started 14 game sand has 3 picks last year, 1 he brought back to the house. He played in 92% of available defensive snaps.
His completion percentage against is 60.6% and was targeted 104 times. Some of that is playing opposite Casey Hayward (49.4%), but most of that is QB's liking their chances.
For reference, All-Pro corners (Miami's) Xavien Howard had a completion percentage of 51.5% and (Rams) Jalen Ramsey was at 50.7%.
