The New England Patriots celebrated their victory in Super Bowl LIII with a parade a couple days after the game itself. They'll likely bask in the afterglow of their big win for a little while longer, but before long, it'll be back to business and the 2019 NFL offseason.
For the other 31 franchises, the offseason has already begun. Most have already spent more than a month surveying the free-agent and draft landscapes, hoping to make up some ground on the Patriots this spring.
While free agency will certainly play a role in shaping the 2019 season, the draft is where the building blocks of dynasties like New England's are found.
