I also always play as the Eagles. While it may be really annoying, what I do is go to the salaries page, find the salary figures for the next year (2020), add them all up on my phone 1 at a time, and that’s how I see my salary commitments for future years.
I don’t know for sure, but in M19 I think the salary cap went up by around $5M each year for like 5 years and then stopped (though I could be remembering wrong).
If it’s the same this year then you could add up all your 2020 contracts, add in the dead money for 2020 (I think that’s visible on the salaries page), and add in the rookie reserve, and then subtract that number from the projected salary cap (which might be the same as the current year cap plus around $5M maybe). What’s left over would then hypothetically be pretty close to your available cap space for 2020.
Either way, if the contracts are done accurately then what you’re experiencing isn’t actually that unrealistic. The Eagles are currently about $20mil under the cap, but they have around 35-40 out of 90 current players on the last year of their deal. Despite losing 35-40 contracts after this year, the Eagles will only have a projected $5 million in cap room next year. The remaining players have such a dramatic increase in pay that they are going to have less cap space despite potentially losing 35+ players to free agency. Though that isn’t accounting for any roll-over cap from this year (but the game doesn’t include roll over cap) or any increase in the salary cap (which the game usually does include).
So depending on any dead money penalties you may have gotten from various cuts, the fact that you have no cap room for the 2020 Eagles isn’t entirely unrealistic. Wentz’ new contract ($18.6M 2020 cap hit), Graham’s new deal ($13.4M), Malik Jackson signing ($10M), DeSean Jackson contract ($8.9M), and all the backloaded deals for Cox ($22.8M), Johnson ($13.5M), Jeffrey ($16M), Ertz ($12.2M), Brooks ($11.5M), Jenkins ($10.9M), and Bradham ($9.8M) are taking up a huge part of the 2020 cap space. (Those are their real life 2020 cap hits, in Madden they might not be entirely accurate).
You’ll probably need to wait until the end of the season and then make some cuts to free up cap space to re-sign your departing players. Or make the cuts now and resign early, but then you have to get through the year without those players you cut.
