Being Linemen, they are indeed required to line up on the Line of Scrimmage before the Snap, unlike the others.
Because this places them nose to nose with the opposing CornerBack ~ whereas the SlotBacks and Flankers are allowed to align a couple steps back, thus affording them more room to maneuver ~ they need to be much bigger.
*Please do note, though: Schematically, the Split End is whoever lines up as the Split End...But for the purposes of these Scouting Reports, I am applying this NomenClature to those who are Split Ends by trade, so to speak: Those whose Skills Sets apply best to that particular Job Description. What their Coaches might do with them, once they're drafted, is another matter all together. Ditto, the Flankers and SlotBacks. In any case, many play multiple Roles.
The most compelling Attributes of a Split End are, in my view, and in no particular order:
Release ~ How Adeptly he employs Burst, Core Strength, Fluidity, & Combat to Dust Off the Defender
Routing ~ How Adeptly ~ Crisply, Intelligently, and Reliably ~ he Runs the Route Tree
Separation ~ Fluidity & Ricochet ~ Explosiveness out'f'is Breaks
Catching ~ Reliability & Technique
Navigation ~ How well he Navigates the Field in Pursuit of Yards After Catch
Blocking ~ Core Strength, Drive Power, Fluidity, & Combat
Routing ~ Incredibly adept and refined for such a shallow level of Experience.
Separation ~ Extraordinary. Again: Raw. But he commands exceptional Fluidity and Burst out'f'is Breaks.
Catching ~ Impressive. Advanced Savvy & Timing, and rapidly improving. Good Hands.
Navigation ~ Adept. Great Potential, once he gets it all together.
Blocking ~ Decent.
To be sure, he was Raw.
But Fuller advanced by Leaps & Bounds in 2012, and in one short Year his Routing and his general understanding of the Game have advanced at an astonishing rate. Combined with explosive Acceleration Off The Line, outstanding Agility & Precision in'is Routes, and rapidly developing Instinct & Timing, Corey Fuller is rocketing towards a potentially extraordinary Future, in my incredibly humble opinion.
This is a Projection.
There are certainly many guys I rank him ahead'f whose Games are more refined.
But of course: All Draft Picks are Projections.
Yes, the world is rife with Potential, much of which goes for naught.
But when I see someone as athletically gifted as Corey Fuller improving at such a torrential rate, my Gut tells me that he is a far better bet than most of the guys who've been slowly improving for a few Years.
In a word: I believe that Corey Fuller is going to become extraordinary.
And I believe he's going to attain that level of Excellence far faster than most would even dream of.
