In general athletic terms I mean size, strength, wing span, speed, hands etc. Kupp isn't the biggest, fastest, strongest, best hands but he was the most productive this year. RAC he is uncanny how he breaks tackles or avoids them altogether. If I had to choose top 5 it would be Adams, Hopkins, Kupp, AJ Brown, Hill with Jefferson right there. That's how I see them being drafted in fantasy next year as well.What are you calling athletic?
His RAC and yards after contact put him at the top of being athletic.
Combine measurables do not equal athletic.
