Denver took care of Jake perfectly in this game tonight and really made it easy for him to shine. First, they run Portis about six straight times to start the game, the Raiders know he's coming, but can't stop him. Then, the first pass play is a play-action rollout where Jake doesn't have to make any complicated reads, just run it or dump it to Sharpe about six yards down field. Touchdown. Then, the Raiders still can't stop the run, they are at the mercy of play action, Jake has his confidence, and they just rolled. They simplified their routes from the Cincy game as well, IMO.
Jake had very good games here too, it's not like he sucked every week. But, clearly, he doesn't have the load on his shoulders in Denver, Portis is the main man. When a team stops Portis early, and brings pressure, that's when Jake will struggle.
