Further to the offense being less painful to watch are the parts that give Raider Nation a reason to believe this offense could actually be dangerous if all the pieces fit into place.
Louis Murphy is a threat downfield, runs smooth routes and has the ability to blow by defenders and shake them out of their shoes. He still drops the ball too much, but he is extremely aggressive and always looking to score, with the skill and willingness to block as well. Murphy has the ability to be a 16+ yards per catch guy, making him the big play threat Al Davis loves.
Darrius Heyward-Bey was is another deep threat that has recently shown an ability to make catches in traffic and use his size and speed to get yards after the catch. He's made some nice catches, and though his production hasn't been spectacular, it is certainly enough to show he's vastly improved and ready to put up some numbers.
Johnnie Lee Higgins appears to have regained confidence as a receiver with some nice plays in the passing game. Higgins has looked just okay returning punts, but if he regains some of his 2008 form he can be electric. I think he's a lock for the roster after his performance (and Yamon Figurs' lack thereof) in the Seattle game.
Darren McFadden has shown he's capable of big games when healthy, which unfortunately isn't too often. A tweaked hamstring limited his preseason reps, but he did show ability to break free and move in space, as well as make defenders miss.
He's looked better catching the ball, but with Michael Bush injured for a period, he has to seize the opportunity to disprove critics that say he's overrated and he goes down far too easily running the ball out of the backfield.
Bush and Chaz Schilens are the most productive and consistent members of their faction of the offense, but won't be available for a little while yet. Still, they are both capable of large gains and big games as well, and the a thin offensive core needs them to return as soon as possible.
Then there's ol' reliable, Zach Miller, the Raiders most productive receiver last year. Jason Campbell loves his tight ends, and Coach Cable stated his desire to have Miller more involved in the red zone. Already we've seen Miller targeted and making the most of it in scoring position, and I expect that translates into a huge season.
There are others, such as Jacoby Ford, Nick Miller, Michael Bennett and Marcel Reece that have shown big-play ability this preseason. Manase Tonga surprised me with his speed and athleticism during a great catch and rumble for a TD in the Seattle game.
While mostly young or inexperienced, the Raiders do have playmaking talent at various positions, but as always that talent must translate to production for it to mean anything.
