Not at all. I think if everything fell in place, they'd be great assets to their teams. I don't think it will though. The guy that I think might have the best season of the three is Aaron Brooks, and that's because he, for the most part, actually plays most of the games. He will also have a big chip on his shoulder (though New Orleans fans will tell you he doesn't care enough about that chip), and it certainly helps having the best 2 WR combo of the league and possibly the best 4 WR combo as well (Anyone who puts anything above Randy Moss and Jerry Porter is just blatantly hating). The issue is if the Raiders, with new coach Art Shell, would utilize those talents in the right way, and they need to balance it out with Lamont Jordan, in order to be effective. Should that happen, I can definitely see Oakland's offense being in the top 5, if not the overall team.
Kurt Warner on the other hand, certainly helps that he has Edge now, but unless they address that O-line, he won't see even 10 games.
Bulger? Meh I think he's declining, but you know, I may be wrong.
