It's the NFL. He is a football player. How redundant. Has he shown an ability to avoid hits and stay healthy or stay healthy while absorbing them?
Sammy is great at beating his man, tracking deep balls, and drawing a safety over the top. All the whilst being ignored for a quarter of the season he had over 1,000 yards receiving. His skill set will force teams to bracket him and that in itself creates the spacing for other guys to benefit.
Sammy is not as big as Julio, Sammy is not as elusive as Odell or Antonio. Those are guys who line up all over the place. Sammy is at his best outside, much like ARob, read the description of the X WR.
