How is that relevant. Chad Johnson, carson Palmer and the offense weren't the reason those Bengals team lost. There defense was really bad.why The Patriots haven't advanced despite having a great offense in the playoffs the last couple years)
Its relevant because he comes from coaching systems that haven't accomplished much. Sure that may be best for that one player, but that doesn't mean catering to individual players is best for the team.
All that being said, I think Chad is progressing and is doing everything he can to work his way into the offense. This isn't the same Chad from when Jackman coached him and this may very well be the most anyone can get out of him.
