What happened: Brock Purdy has 789 passing yards on 72.3% completions with 10 total touchdowns against one interception through three games. Bryce Young has six big-time throws to one turnover-worthy play despite facing the league's highest pressure rate.

Why it matters: Their average times to throw sit within 0.02 seconds despite the pressure gap. Brock Purdy's 89.8 offensive grade backs the fast start as more than box-score noise.

What to watch: Next is whether Young gets cleaner protection and whether Purdy holds the league touchdown lead past Week 3.
