Obviously, being in attendance does not mean that the Bills will draft any players from Maryland but their top prospect could be a good fit in Buffalo.
The Terrapins top prospect is free safety Sean Davis. In 2015, Davis recorded 88 total tackles, three interceptions, three passes defensed, one sack, five forced fumbles, and 4.5 tackles for loss. Davis' five forced fumbles were second in the NCAA. In his career, Davis had 319 total tackles, five interceptions, 14 passes defensed, 2.5 sacks, seven forced fumbles and 10 tackles for loss.
Davis stands in at 6'1" and 201 pounds, and is big hitter who has experience playing cornerback and safety. The biggest knock against Davis is that he allowed 614 yards in coverage last year per NFL.com. That said, Maryland had Davis playing at cornerback this season and he's best suited as a safety.
Buffalo's top three safeties include Aaron Williams, Corey Graham, and Robert Blanton. The trio are capable of handling the majority of the workload at safety in 2016, but the Bills need to add someone who could compete for a starting job by 2017. Davis is projected to be selected early on day three of the draft and fits this criteria.
Update: Buffalo sat with Yannick Ngakoue at Maryland's Pro Day according to Tony Pauline. Ndakoue had 13 sacks and 14.5 tackles for loss with Maryland in 2015. Although his stats jump off the page, he's viewed as a day three prospect in the draft.
