The Raiders are a running team. Unfortunately, the Packers are a scoring team. Being down by 17 forces you to pass(unless you're John Fox).
I think pressuring the QB is usually the best way to slow down an offensive juggernaut. Bust his *** repeatedly. Even at the whistle. Make him uncomfortable.
It doesn't look like he's going to progess much but I'd want a better hitter at 1B. If nothing else, start him in AAA and call him up after 20 games if he's your best option.
