An axiom of those of us who have covered the NFL draft for a long time is simple: “Size is not a skill.” This has been especially true for positions where fans and mainstream media can get tantalized by a player’s physical traits including quarterback, wide receiver and defensive back.
The premise is accurate. Just because a player is big, doesn’t mean they are good at playing football. That also applies to speed. A really fast player doesn’t automatically make them good at the football skills necessary to play the game at a high level.
That doesn’t mean size and speed are not beneficial, it just means that have to be used properly for it to matter. Vernon Gholston and Stephen Hill are two easy examples.
