There’s definitely a youth movement in Cleveland and Los Angeles. According to data released by the NFL on Thursday, the Browns had an average age of 24.17 on their Week 1 roster, making them the league’s youngest team. The Rams – who are directed by the league’s youngest head coach – were not far behind with an average age of 25.11. 
As a whole, the game is younger than ever. This year, there a total of nine teams started the season with an average age less than 26. A few clubs are bucking the trend, however. The Cardinals had the “oldest” roster in the NFL with an average age of 27.47. Arizona had 14 players at the age of 30 or over, tying them for the league lead with the Ravens.
The league also compiled data on the colleges with the most players in the NFL. This year, Alabama and LSU tied for the lead with 39 each. LSU had sole leadership atop the perch from 2014-2016, but they now have the company of another SEC school.
