I'd add it is time to change training camps. The CPU only can get maximum sliver xp, as you're getting gold each week. Bring back the Mut 20 coins coaching camps, and rework the way the recent ones work. We could have the training camps at the onset of the pre-season. Rework the weekly ones. 

Possibly less xp for each week basis, and much more xp for throwing for 4 or more TDs, or becoming over 3 sacks etc.I agree with what you mentioned but if a few no name gained 15 overall points within a season and shit in my team I'd be pissed and assert it was unrealistic. I believe other Madden players would state the same.

I am a big fan of this breakout system, however I'll agree that it is still absurdly hard to upgrade people who deserve it, like Minshew. I will say however, Minshew plays better than his overall lol I agree that the trading is weirdly limited. I understand that's probably a good deal but there should be results, and also restrictions to trading. I feel like you there is no in between and have to overpay in a trade or can get something good.

It is because of the XP system works. The end of year awards are so heavy XP they give that they can turn a guy into a much better Madden participant, particularly if he wins multiples. If a guy ends up becoming +10 OVR through the season, getting an additional +5 or in the close of the season could be too much, so they just create the XP through the madden 20 mut coins year meh to make up for the ending of season XP gains. Which means when a man has a monster season a bit that is fantastic can be improved by him, but if he's got a season that is fantastic and does not receive the awards he will not progress much.
