The education of NFL rookie wide receivers involves plenty of trial, error and confusion.
It's a complicated position and there are a lot of adjustments to be made.
It's the growth and determination through those learning moments that coaches and executives look for.
In the case of Texans wide receivers Will Fuller and Braxton Miller, both displayed potential after being drafted by the AFC South champions last season.
With 4.28 speed in the 40-yard dash, Fuller emerged as a dangerous deep threat who was difficult to corral in the open field.
What held Fuller back from making more of a splash as a rookie after being drafted in the first round out of Notre Dame was a tendency to drop long throws and nagging knee and hamstring injuries.
