As it relates to bolded area.
Hyde had some versatile experience playing CB, slot and Big Safety for GB before coming to BUF and was unproven as a safety. He was in fact a late 5th rd pick in 2013.
Poyer was a 7th Rd draft pick in 2013 by Eagles, cut and picked up by CLE in same year. He was unproven as only 10 starts in 4 years.
I trust the Bills staff in developing DBs for their system and believe Hamlin or Johnson could step in if needed this year.
