Team sources are saying that Richard Marshall had fallen out of favor with the coaches and was basically the nickel corner. He even lined up at safety yesterday during practice. For a guy who was listed as the starter at the beginning of camp, that's not good. Basically another player in Coach Philbin's doghouse.
Sorry to contradict you, but he actually came to our team this way. He was known as a player who was flexible between safety and nickel corner. Last year, he had such a good camp they got rid of Vontae and moved him to the outside but he wasn't known for this.
I think this release is as much of a statement on how well our safeties are playing (and their backups). The need to pay a guy a bunch of money to be a flex player isn't there.
