The Bengals have shown a real committment to their stars; last year a huge deal to Carson Palmer to make him a Bengal for his career (hopefully a long and storied career after a full recovery from the knee injury), and an extension on Marv's contract. Now 85. Hopefully that Sam Adams character can help out the D, because the offense is potent as all-get-out.
It appears the plan is to get the key offensive stars locked up and then put the rest of their energies into building up the defense.
