Salary Cap fact versus fiction

[Creeper]

The Eagles short-circuited a very talented roster and have now lost about 35% of the starters off their SB team.
Jeffrey has given them 1600 yards in TWO seasons. That's a bad return on investment for what they are paying.
If they cut Jeffrey this year they eat 21M in cap space.
Yet they are scheduled for 15M, 16M and 16M in cap hits for a guy 4 or 5 years form his career best season.

Jimmy didn't have a cap at all and STILL built his team primarily through the draft.
The trades were merely to acquire draft picks 9 times out of 10.

The Eagles won a Super Bowl. Perhaps they will not be as good this year as they were last, that remains to be seen. But the moves they made prior to 2017 were good enough to get them to the Super Bowl and win it. That is the goal. When is the last time Dallas won a Super Bowl?
