The article is using a very far fetched example which HS kids using basic math can avoid, and will never even remotely come close to happening. The rollovers are all calculated by team projecting their needs and cap space over the next two years, and what they want to do with it.
Do you really think any NFL team, in a billion dollar industry, does not know what is coming?
Thanks for making my point. Do they have an idea what is coming? Yes. But they don't know exactly, so they have to plan for every contingency. Which is why if they plan on having to resign Tannehill to franchise QB money, in either of their next two off seasons, they can't blow all of their cap now on long term contracts for the linemen that Armando is complaining about. Signing players to long term deals, with prorated bonuses against the cap, and then releasing them before they expire is about the worst thing you can do for your cap. This is exactly what the FO is protecting themselves against.
