Teams have to put up every dollar pledged in guarantees into a bank account.....some teams don't have the 50m in cash just lying around like DAL does...they could use it to an advantage but they don't
they can also give huge signing bonuses to lessen the cap hit and restructure all their contracts to create even more room...they could spend 150% of the cap indefinitely...our old friend XWalker used to put up a spreadsheet showing how easily it could be done
The salary cap is a speed bump, not a barb wired fence but DAL has the fanbase sold on acting like a small market team is better than acting like the largest revenue team in sports....they keep more of the profits and you guys not only accept it but berate those that actual complain about it...it is bizarro world
