Player ratings
 

Take two guys with current ability of 45. How can one have so much more red than the other.

Exhibit A's and B's player card numbers
55 33
46 54
60 22
10 20
32 71
41 31
50 55
8 100
25 81
28 60
23 33
61 15
63 36

Player A's column totals 502 points
Player B's column totals 611 points

Are the unseen bars being taken into account here? Player A's unseen bars are much better than player B's?

The other explanation I thought of is some ratings count more than others. Player B's 100 in timing counts less as it doesn't matter as much as some other ratings? But then player B is also much better in ratings such as sense rush and read defense that I personally think count for a lot.

This is definitely part of the answer.
