PSA Comparison 1970 Kellogg's Baseball vs. Football

There have been 29,040 1970 Kellogg's baseball cards graded.  With 75 cards in the that is an average of 387 submissions per card.  As far as cards graded as 10s, that is about 56 per player on average.

For 1970 Kellogg's football cards there have been 17,383 cards graded.  With 60 cards in the set that is an average of almost 290 submissions per card.  As far as cards graded as 10s, that is over 53 per player on average.

I was surprised to see how many of the 1970 Kellogg's football cards have been graded relative to the baseball ones.  There is also a similar disparity in the number of PSA 10 cards in the football set.  There are a bunch of cards with 25 or less 10s - Butkus (20), M. Garrett (12), C. Garrett (20), Alworth (20), Bell (15), Nobis (22) and Meador (24).  I'd like to see where location on a sheet impacts the grades.
