EOS reported this week that Bravo was seeing time in the 4-3-3 at CB. Harrison is eligible to return for the Philly game but he was held out of practice the other day for "rest" and PV has said that he is unsure if he will make the 18.
Good stuff. Bravo as CB in the 4-3-3 is an interesting choice. I could be wrong, but I think he's done a fair amount of sliding back in the 3-2-2-3 anyway. He is a guy who can be very effective distributing out of the back, so if he can handle the additional duties that come with being a CB (e.g. not letting people on-side), it can be a profitable experiment.
