Looking at the projection for 2015 is not really an apple to apples comparison. Some teams have several big name free agents while other teams have most of their big name players under contract. Suh will not show up under the Lions 2015 projection, but it they want to keep him that's at least 12M per year average for his contract and it will not show up in current projections of their cap. What you're referring to are the problems related to signing players to bad contracts. If you don't sign the right players then you won't be good regardless of the cap issues. You're paying current players with future cap money and the cap goes up over time. That is an advantage when used to sign productive free agents. Most people either can't or won't try to understand, but the bill never really comes due for money that is pushed into the future if it is managed correctly.
