Tom Brady is set to make his broadcasting debut as the Cleveland Browns play host to the Dallas Cowboys in “America’s Game of the Week” on FOX.

Brady previewed the game, including why Week 1 is a challenge for every team, in an exclusive video on Saturday, which you can watch here.

Brady’s first game behind isn’t the only storyline heading into this epic clash, though. Here are some others:

— Cowboys QB Dak Prescott took the in Cleveland just hours after signing a four-year, $240 million extension with $231 million guaranteed. At $60 million per year, it’s the richest contract in NFL history and keeps Prescott from becoming an unrestricted free agent next offseason, where he may have received an even bigger contract on the open market. Go here for more about Prescott’s record deal.

— Prescott is not the only Cowboys star playing under a new contract on Sunday. WR CeeDee Lamb has been clear that he would be ready for any workload after missing all of training camp in a contract holdout. Lamb got a $136 million, four-year contract, a tick below the $140 million deal signed by Minnesota’s Justin Jefferson. Now Lamb starts the work on an encore to his breakout season. He led the NFL with 135 catches and had 1,749 yards and 12 touchdowns. The 25-year-old has increased his numbers in all three categories each of his first four seasons.

— Browns QB Deshaun Watson started for the first time since breaking a bone in his right shoulder in November. Watson had surgery, ending his second season with Cleveland after just six starts. While disappointing, Watson ended on a high note by completing all 14 passes in a second-half comeback win at Baltimore despite playing through the injury.
