WHO WILL BE THE DARK HORSE THIS SEASON???

Each season (okay, well *most* seasons) we seen someone come out of left field and become an instant star on the field.  Usually it's some unknown player that went undrafted, or a lesser-known free agent signing during the offseason.  This thought has been nawing at me over the past month or so, and I'm curious to see who it might be.

Any thoughts?

I'm thinking maybe Hayden Hurst, but that would almost be expected.   I have a feeling it will be fun to watch Bryce Young find his brand new "favorite target". 

Jonathan Mingo is an exciting prospect for me.
