There are resources on MUT.gg...there are resources within the game , etc. but I see a lot of people misunderstanding what a lot of abilities, traits, and ratings mean.....
I see people writing things like Deep Route KO is better than Deep Out Zone KO because it covers ALL routes. One is used in man cvg , one in zone....really not comparable in that sense.
Another example....someone wrote that a particular WR was not good because his makes possession catch trait was "no". Unless you are allowing the CPU to catch the ball for you this is not relevant.
The resources are there guys...for example....
