For the stats filters one of the options is Opponents. I feel this feature is lacking.
There is now way to edit/sort this feature, which is fair enough (even though having some filter options would be best), but it seems it is preset to automatically be sorted by O-Rank. I feel like this could be improved upon by instead having it auto-sort by season rank.
When you go back and look through the O-Ranks you'll see that having it sorted by O-Rank makes it so that guys who had great O-Ranks and are either injured or have severely struggled are in the list (first 25 for example), but if you had it by season rank these types of players would over time be filtered out and moved to lower on the list.
