Top Heavy
“Top Heavy? are those positions which are almost entirely addressed in the early portion of the draft, mostly via the first round. The inference is that these are positions that need to be addressed very early in the draft. This group includes quarterback, running back, #1 wide receiver, defensive tackle, and offensive tackle.
Essentially what we see encompassed here are high-profile skill position players (QB, RB, and WR) and guys with exceptional athletic ability for their size (DT, OT). These are the types of players that are hard to miss when evaluating talent. Even a small college skill position player who puts up eye-popping statistics will grab the attention of scouts, so exceptional skill position players will rarely get overlooked. Those that do slide will 1) have durability (or “character?) issues that have kept them off the field, 2) be somewhat raw in terms of technique, or 3) have been misfit to their college offensive system. Meanwhile, the “Planet Theory? guys that you’ll find excelling at offensive and defensive tackle are also going to make extra large blips on scouts’ radar screens. (The Planet Theory is Bill Parcells’ philosophy that there are so few men both large enough and athletic enough to be NFL linemen that they are intrinsically valuable.) They may not have impressive statistics to shed light on their talents, but their “measurables? will make them very hard to miss.
The quarterback position is especially top heavy. Exactly half of the starting QBs in the NFL (when this data was collected) were drafted in the first round. ...
... The QB position is by far the toughest to fill, and most teams are (and should be) willing to fill it by any means necessary. First round QBs are no sure thing, but anyone picked after the first round appears to be a very long shot that will require several years of development. And even those late round guys that do work out will probably have to move to a new team to be successful. The bottom line here is that until you’ve found your guy you should jump at any opportunity to acquire a quality starter, be it early in the draft, late in the draft, via trade, or through free agency. Don’t pass on a QB early in the draft because you also like a guy that could be had later. If you are really in need of a QB you should probably draft them both...
