Draft tiers show depth of this draft

All 32 NFL draft rooms are fully stocked with prospect rankings -- both by position and regardless of position -- come draft day. In addition, general managers package these rankings in a number of different ways to streamline the information and help maintain perspective when weighing value versus need.

The stacking-the-board documents (offense and defense) that we rolled out earlier are an excellent example of one way to organize rankings. This method gives the evaluator a quick way to compare player values (round by round) from one position to the next.

Tier rankings are yet another tool for decisions-makers to call upon to help assess the areas of strength within a given draft class. For example, this year's group has just four elite prospects, in our opinion. But it doesn't take long to realize how strong this group is as a whole. By the time we reach RB Jahvid Best at the bottom of Tier VI, the 2010 class already offers approximately 10 more prospects of value than usual.
