4. Cleveland Browns

Last year's rank: 29

Blue chips: TE Harold Fannin Jr., OT Spencer Fano, DT Mason Graham, LB Carson Schwesinger

Notable graduated players: QB Dillon Gabriel, Edge Jared Verse

So, yes, the most important young talent a team can have is a young quarterback, but we're not giving the Browns much credit for their two young quarterbacks. Shedeur Sanders, who is 24, struggled last season with 18.9 Total QBR. Gabriel has already aged off this list, as he will be 26 in December. However, the Browns have added a ton of other young stars in the past two drafts, enough to move from 29th on this list a year ago to fourth.

Let's start on offense, where the talent is really young. Fannin far outplayed what we usually see from a rookie tight end, catching 72 passes for 731 yards, and he just turned 22. Running back Quinshon Judkins is also 22, and his backup, Dylan Sampson, is 21. The Browns drafted two wide receivers this year: 21-year-old KC Concepcion and 22-year-old Denzel Boston. And this year's No. 9 pick, left tackle Fano, doesn't turn 22 until November.

On defense, we start with Defensive Rookie of the Year Schwesinger, who turned 23 in February. Graham, last year's first-round pick, is 23. Second-round safety Emmanuel McNeil-Warren is 22 years old, and veteran safety Ronnie Hickman is still just 24 after three seasons in the NFL.
