Just be very, very cautious about the "ranking" and rating of recruits. Nobody knows which guys have the guts, grit, self control, heart and even athletic ability to be top players at the college level. Add to that the academic needs of going to a university like the U and all the off the field, out of the classroom distractions that exist for all new students and you end up with a very, very imperfect guesstimate of which players might do well in BCS football. Give me a dollar for every 'can't miss' recruit who misses and I will gladly give you a dollar for every one who makes honorable mention All Big Ten.
If you look at recruiting in those terms, it can be a little fun. Otherwise, it is a mugs game. 'Yes' you would rather get the 'highly rated' guys rather than the not 'highly rated' guys, on average. However, you will not know whether a guy was really a great recruit until his days at the U are over.
