Russell has the worst accuracy in the nfl. hands down. he holds onto the ball too long but they have a good running game to protect him, not unlike the skins. He has a quick and powerful release.
campbell is more accurate (not saying much), more mobile (by a longshot), but has a sloooow release.
they're very similar really. Neither have shown that much leadership or off the field dedication. Neither have lived up to their potential and neither likely will anytime soon.
the raiders do look better than us tho...
