Rousseau recorded six tackles (all solo) including 3.0 sacks, and a forced fumble during Sunday's 34-28 win versus the Cardinals.
One of his sacks in Week 1 came on a foot race to the sideline with Kyler Murray, whose exceptional speed Rousseau was basically able to match after shedding right tackle Jonah Williams (knee). It's a dynamite start for a player looking for the first double-digit sack season of his career. He'll be pursuing Tua Tagovailoa when the Bills trek to Miami in Week 2.
