Ed Oliver

Oliver has yet to take a snap in the NFL but the expectations for the No. 9 pick in the 2019 NFL draft sure are high. Oliver is set to take over at the three-technique defensive tackle position with Kyle Williams retiring. But, Oliver knows he's going to have to work to get to Williams' level of play.

"What do I think when I hear that I'm Kyle Williams' replacement? I think that Kyle Williams is a great player," Oliver said. "I think Kyle Williams will wear a gold jacket one day. I just want to come in and compete and help the team in any way possible. I don't even think about that. Kyle Williams is in a league of his own that I haven't even come close to touching. I just want to come in and compete."

Oliver is also going to need to beat out veteran Jordan Phillips for the starting job. He has a relentless motor on the field, the same way that Williams had. Oliver will have to prove his doubters wrong his first season and show he's capable of producing the same numbers he did at the University of Houston.

Jerry Hughes

Arguably the Bills' best edge rusher last season, Hughes will need to show he's capable of producing the same numbers he did as he enters his age 31 season. Hughes recorded his highest sack total since 2014 with seven this past season and the Bills expect better production with more talent around him after signing him to a two-year extension this offseason.

With the retirement of Kyle Williams, Hughes is now the longest tenured Bill.
