With 16 teams in action Friday night, there were no shortage of storylines to follow. But let's be real: Nothing mattered more than the three quarterback battles.
Mark Sanchez threw a pick-six on his first drive, and he outplayed Jets rookie Geno Smith overall. (Smith also suffered an ankle injury.) Blaine Gabbert threw for just 19 yards in 10 attempts, including an interception. That's hard to do. Chad Henne looked much better, but the Jaguars scored just three points on the night.
Here's what else we learned Friday night:
Undrafted rookie wide receiver Kenbrell Thompkins backed up all the training-camp hype with four catches in one drive. Undrafted rookie Zach Sudfeld started at tight end; rookie Aaron Dobson caught a 23-yard pass from Brady, and second-year pro Shane Vereen caught a touchdown while lined up at wideout. This offense looked very different, but it was totally fascinating.
- Philadelphia didn't huddle a lot or take many snaps from center, especially when Foles was in the game.
- The first-round wide receivers impressed for both teams. After returning the opening kickoff 50 yards, Vikings rookie Cordarrelle Patterson hauled in four passes for 54 yards and just missed another sideline grab. Although he's playing behind Jerome Simpson at this point, Patterson's talent will be hard to keep off the field. He's not quite as freakishly athletic as Julio Jones, but there are similarities in their games.
- Christian Ponder attempted just two passes, including an interception off Simpson's hands, before he was replaced. Backup Matt Cassel was a misleading 12 of 19 for 212 yards and one touchdown with a troubling interception. Cassel was shaky against pressure; the majority of his yards came after the catch on big plays by Stephen Burton and Zach Line.
- Sanchez bounced back nicely from an early game pick-six to complete 10 of 13 passes for 125 yards and the Jets' first preseason touchdown since 2011. Smith went three-and-out on two of three series before exiting with a sprained ankle. Sanchez gets the decisive edge for the preseason opener, though Smith expects to be back for the Jaguars game next week. Greg McElroy enjoyed a fine performance as the third quarterback.
- Armanti Edwards' improbable run at Carolina's No. 3 receiver job continued with two catches for 38 yards.
- Playing it cautiously, the Packers sat Randall Cobb (biceps) and Eddie Lacy (hamstring) for the preseason opener. James Starks started at running back, with rookie Johnathan Franklin as the first back off the bench. Neither took advantage of the opportunity to gain on Lacy and injured incumbent DuJuan Harris.
- The Cardinals got a long look at fifth-round pick Stepfan Taylor, with Rashard Mendenhall, Ryan Williams and Andre Ellington all banged up. Taylor isn't a dynamic talent as a runner, but his excellent pass protection and route running skills could land him the backup job if Williams' knee doesn't cooperate.
- The Tony Romo-to-Dez Bryant connection showed no signs of rust, the two Cowboys picking up where they left off in the second half of last season. Bryant looks even more confident and physical than he did in his breakout season, bullying the Raiders' secondary for 58 yards and three receptions on one late first-quarter drive.
