What happened: PFF credits Collins with nine contested catches in two games, with Olave and Wilson next at eight apiece. Pickens sits at seven, followed by a five-player tie at six for fifth.

Why it matters: Winning in tight coverage signals go-to usage on third downs and in the red zone. Collins is producing on a different per-game pace than every other leader, including Olave after his four-year extension.

What to watch: Watch whether Collins holds the lead with a full Week 5 workload and whether Olave or Wilson passes him on volume.
