Buffalo Bills general manager Brandon Beane acknowledged on Thursday that the team lost a top-end receiver when it chose to trade Stefon Diggs to the Houston Texans, hasn't replaced him with a player of that caliber and is still in the market for wideouts.

"I get that you're talking about a guy for his first four years here was in a No. 1 role. We have not filled a No. 1 role," he told reporters. "I would say we have a group of guys as we sit here today who we believe bring different skill sets. We like the group. Would we like to add to it at some point? Yes. But I'm not sitting here thinking we have a glaring hole. But I get the question, and I get the perception."

Wideout is a major need in Buffalo. Josh Allen will go from having Diggs and Gabe Davis atop the receiving depth chart to Curtis Samuel, Khalil Shakir and Mack Hollins, alongside tight ends Dalton Kincaid and Dawson Knox.

That lack of talent at wide receiver is why most mock drafts believe the Bills will address the position early in this year's draft.

The B/R NFL Scouting Department projected Buffalo to take Florida State wideout Keon Coleman in the first round, noting that he "helps create a larger margin for error as a downfield target with a ridiculous catch radius."

Peter Schrager of NFL.com projected the team to select Texas wideout Adonai Mitchell, writing: "Big, fast and physical, Mitchell garners plenty of interest in league circles. This is lower than where some other mock drafts have him going, but I could see him lingering in the mid-to-late 20s."

Field Yates also picked Mitchell to the Bills in his three-round mock draft with Mel Kiper Jr. for ESPN.

"There is a lot of different style receivers from size, speed, quickness," Beane told reporters when talking about this year's wideout prospects. "Some have better hands, some are not great RAC (running after catch)—they've got good hands, but you're probably not getting much. Some other ones maybe have less size, but if you can get the ball in their hands, they kind of turn into a little bit of a running back."

The Bills could also choose to trade up from No. 28 if they've fallen in love with a prospect, or wait it out to see who falls in their lap. And trading back to accumulate draft picks, while hoping to identify steals later in the process, is always a possibility.

It's unlikely the team will directly replace a four-time Pro Bowler like Diggs. But there's little doubt that more weapons are needed for Josh Allen.
