Cleveland Browns
Biggest move: Kevin Stefanski has used multiple tight ends -- fullbacks as well -- as often as any coach in the NFL in his two seasons with the Browns. But Cleveland kept only two tight ends (David Njoku, Harrison Bryant) and waived its only fullback, Johnny Stanton, a fan favorite. The Browns are shifting to a more receiver-heavy, wide-open scheme. But wide receiver is the team's biggest question mark. And backup Jacoby Brissett -- not Deshaun Watson -- will be quarterbacking the first 11 games. -- Jake Trotter
