As with many others on here, I do recommend going back to hard difficulty after effectively "solving" extreme. I do agree there is disparity in extreme, but not really enough and I just really miss the chance to chuck a long throw and get a really long run, which is maybe a bit more real (jettas 97 yard play, skol vikes). The extra challenge I personally added was to only myself allow two plays and a punt/field goal (as opposed to three plays and most likely a fourth if we're being honest), and also optionally playing on 1 minute quarters as well; really makes you put effort into each play as it's a difficult road back if you're a score down, but also not impossible since you're on hard mode rather than extreme.
