In order to break down each prospect, the National Football Post uses a numerical grading scale which focuses on evaluating prospects’ potential in terms of “starter caliber,” “dirty starter caliber,” “possible starter caliber,” “backup/depth caliber” and “free agent caliber.”

Here is the full grading scale with an explanation of each grade.

NFP Numerical College Grading Scale

Starter Caliber

8.0 Starts first game as a pro…a prospect who possesses rare physical attributes that have an obvious impact on the game…will instantly become one of the best players at his position in the NFL.

7.5 Becomes a starter in his rookie season…a prospect who possesses physical attributes that will create mismatches and have an obvious impact on the game…will become a premier player in the league.

7.0 Starts in first game as a pro…a prospect who possesses physical attributes that will create mismatches vs. most opponents…a featured player on a team.

6.9 Becomes a starter during his rookie year…a prospect who possesses physical attributes that will create mismatches vs. most opponents…a featured player on team.

6.8 Becomes a starter in his rookie year…becomes a solid NFL player who has no real weakness…can’t be exploited or consistently taken out of games.

Dirty Starter Caliber

6.7 Contributes first year and starts second year…must be able to get on the field and make a contribution as a rookie…expected to start his second year in the league.

6.6 Contributes first year but may need time to become a starter…has the ability to become a starter and will be expected to assume a starting role.

6.5 Clean player who is inconsistent in his play due to character, alertness or competitiveness…has all the physical tools needed to become a starter…if he overcomes his deficiencies, he will be a star in the league…if he doesn’t, he’ll be a complete failure…NO middle ground.
