What happened: Jason Kelce said rookies learn from veteran teammates as well as coaches. He cited Kirk Cousins' presence as a resource for Fernando Mendoza.
Why it matters: Mendoza is entering the NFL behind a 15th-year quarterback with 167 career starts. Cousins began camp atop Mendoza on the depth chart, giving the rookie time to develop without immediately directing the offense.
By the numbers: Cousins entered 2026 with 44,700 passing yards, 298 touchdowns and a 66.7% completion rate across 174 games. Mendoza joined him as the 2026 No.
What to watch: Preseason repetitions and subsequent depth charts will show whether Mendoza closes the gap before the opener.
