Stefon Diggs
If Josh Allen is able to have a Hall of Fame career, it will likely be tied closely to Stefon Diggs, his top receiver. The Buffalo Bills had a great quarterback-wide receiver combination in Jim Kelly and Andre Reed and the duo of Allen and Diggs look to have that same kind of magic.
In their first season together, these two broke numerous single-season franchise records with Stefon Diggs shattering the reception record with 127 receptions, 27 more than the record set by Eric Moulds in 2002. He also set the franchise record for receiving yards in a season with 1,535.
After five good, but not great, seasons with the Minnesota Vikings to start his career, Diggs showed just how good he could be with the Buffalo Bills last season. He is still in the prime of his career and only 27 years old and similar to Josh Allen will need to add more awards like Pro Bowls and All-Pro selections to his resume.
However, as long as he has Josh Allen throwing him the ball he should have a good chance at building a Hall of Fame career.
