What happened: Pregnon drew early praise for his pass protection in his NFL debut at left guard. The review centered on multiple dropbacks with a clean interior pocket.

Why it matters: That matters for the Jacksonville Jaguars because steady interior protection is one of the quickest tests for a rookie lineman. If that holds up week to week, Jacksonville can keep more stability on the left side of the line.

What to watch: Watch whether Pregnon's pass sets stay this clean over a larger workload next week. His hold on the left guard role will matter as Jacksonville settles its early-season front.
