2. Wide Receiver
The wide receiver position has a number of questions after Stefon Diggs that will have major impacts on the success of the offense and the passing game. The Bills are going into this season with Gabe Davis as their second wide receiver and the hope is that he can correct a drop issue that plagued him last season.
After Gabe Davis, the Buffalo Bills don't have a clear answer at slot receiver but the competition likely will be between Trent Sherfield and Khalil Shakir. However, whoever wins that job will still probably split snaps with Dalton Kincaid as the Bills utilize more two-tight end sets this season.
The Bills also brought in Deonte Harty but he has had injury issues previously and been on injured reserve in two of his four seasons in the NFL. After Harty is rookie Justin Shorter and a number of undrafted free agents.
While the Buffalo Bills have options, they probably have just as many questions and this could cause problems as the season goes along.
