Im not worried about Cary Williams.
Pre-season for vets is more of a focus on weaknesses, where younger players are about identifying strengths.
Williams is a vet who has started 64 games against some big time WRs in the AFC North and NFC East.
He also as yet to play with Earl Thomas in a real game and he's polishing new techniques and building chemistry with the squad.
Its naive to compare him to Maxwell, even though he was just as average as Williams last year, and Simon who have multiple seasons in the system.
We'll see though, I feel if the Seahawks were truly worried they would have trotted Williams out vs the Raiders to get extra work. But he sat out with the rest of the starters.
