If I had to guess what UDFA will most likely stick with the team I would guess Tariq Thompson.
I became a fan through mock drafts and then watching videos (I think this happens to all of us).
Buffalo is weak at S Depth. Look for him to push Siran Neal for big nickel, and Josh Thomas/ Jaquan Johnson as S depth.
He may not make the 53, but the PS. From The draftnetwork.com:
6'0 200 - 210 lbs. Good size. 4 year starter. All this guy does is produce, but his pro-day was terrible.
Career at SD State
Per Sports Reference:
210 Tot Tak/ 146 Solo/ 64 Assist/ 11 Tack for a loss/ 1 sack/ 11 INT/ 23 passes defended/ 5 Fumble Recoveries/ 5 Forced Fumbles/ 1 TD
PER ESPN:
217 Tot Tak/ 153 solo/ 64 Assist/ 1 sack/ 6 FF/ 4 FR/ 12 INT/ 23 PD/ 1 TD
I hope it translates to the NFL
