Except Jackson has not shown any of these things. He did nothing for Campbell when his ancient offensive philosophy should have aided him greatly. Palmer improved once he left with McFadden wrestling injuries again all year.
Jackson hasnt been a great service to any QB he's been entrusted with. Instead, he elects to protect them from themselves by hiding them away and running the football. Palmer may have been average, but his skillset was a perfect fit for Oaklands offense. Jackson just plays old man football, and there isn't anything to suggest otherwise.
Could he adapt his philosophy? Sure. But theres nothing on his resume' to suggest he will.
Campbell is on his third team in seven years and has done exactly jack poo in the league. He looked terrible for the Bears in his recent playing time as well. I doubt there is anyone in the NFL who can do much for him.
Palmer eh, he supposedly improved but his team only won 4 games this year once Jackson left. Great for him?
Edit: Looks like it's all a moot point now. Or not..
