Ladd McConkey
Ladd McConkey is the fifth-best wide receiver in this draft class after those Top 4 and would be a great addition for the Buffalo Bills. He is a great pass catcher who is able to create separation with his route running.
The Bills have been desperately looking for a reliable pass catcher in this short to intermediate part of the field since Cole Beasley. McConkey could certainly do that but the question for Joe Brady and the coaching staff is how he works him onto the field alongside Curtis Samuel and Khalil Shakir as all three are best in the slot.
Adonai Mitchell
Another wide receiver that could be an option for the Buffalo Bills is Adonai Mitchell out of Texas. He has the prototypical physical skill set teams look for at wide receiver at 6'2" and 205 pounds while running a 4.34 40-yard dash.
The biggest concern for Mitchell is that the production has never really lived up to its potential during his time at college. If teams can bring all the pieces together, he will be an excellent wide receiver but that is a big question.
