Go play the "Epic Challenges"
You will get matched up against 87 overall CPU players...not high rated players, but 87 overalls...
However, these players will perform much better than 87
These arent like those Goon Guardian challlenges against Superhuman 99 overall Steve Fletcher with his 99 overall goons...those challenges are hard, but at least we know we are playing 99 overalls
These 87 overall CPU players will....
They will catch everything in traffic
They will shed your oline like swiss cheese
But even straightforward, supposed non RNG ratings like speed
Their slow DBs will outrun your fast WRs - even a 5 speed diff wont matter
Their slow WRs/TEs will outrun your fast DBS
.
This is the most valid proof EA can secretly adjust players in game performance better than their actual ratings
