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 ~ Magnificent. Reliable, Disciplined, and perhaps the crispest Router in the entire Class.
Separation ~ Outstanding. Fluid & extraordinarily Explosive out'f'is Breaks.
Catching ~ Adequate. And steadily improving here, as well.
Navigation ~ Phenomenal. An absolute master of the Open Field, and not afraid to go through you, either.
Blocking ~ Mediocre results, so far, but outstanding Effort, and he's sure to get good as he strengthens.
This is the kind of Player who does the thousands of little things ~ and plenty of big things ~ that make the crucial Difference in the Championship Quest ~ the kind of Split End you pray for.
He's a Natural Born Leader, gets better every Year, and while he doesn't have the Long Speed that makes folks salivate, he will consistently Move The Chains, throw down Blocks, and make huge Plays when you need'm most.
Perhaps best of all, considering the notoriously lengthy Incubation Period of most "Wide Receivers"?
He is ready to start on the OutSide today.
