Seems like Simpson's last 5-6 games is what he can expect at Arizona. Which was a weak OL and no running game. Most scouts say he needs to sit behind an experienced starter. Well, if that all doesn't spew joining the Cardinals, I don't know what does (sarcasm).
If we don't have a long term plan for him to sit for at least a year, we should pass. It's just our luck that the "perfect" scenario for Simpson would be drafted by the Rams and sit behind Stafford. Then we will see the cerebreal mind that Simpson has tear us apart for years to come.
