The following system is used for rating Michigan prospects. Ratings are determined by the author of this blog and are subject to change throughout a player's recruitment.
100 = Best prospect in the country at his position; high likelihood of 1st round NFL potential (Ex: Charles Woodson)
90-99 = Outstanding starter in Big Ten; likely All-Big Ten and All-American; high likelihood of NFL draft potential (Ex: Brandon Graham)
80-89 = Very good starter in Big Ten; good chance of All-Big Ten; some NFL draft potential (Ex: Jonas Mouton)
70-79 = Solid starter in Big Ten; some NFL draft potential (Ex: Brandon Minor)
60-69 = Average starter in Big Ten; little NFL draft potential (Ex: Mark Ortmann)
50-59 = Below average starter or good backup (Ex: John Ferrara)
40-49 = Average backup or solid special teams contributor (Ex: Darnell Hood)
1-39 = Below average backup or special teams contributor (Ex: Brandon Logan)
NOTE: Examples are based on a player's completed college career, and NOT his potential as a recruit.
