He had a second round grade by most analysts prior to his injury, but the injury dropped him several rounds. Because of this, I had us taking Broyles with our second pick in the fourth round, and it wasn't hard to believe he'd be there. But that was before he showed so well at his pro day, proving to scouts that he would, indeed, be ready to go.
His stock is climbing steadily at this point, and I don't think there's any way he makes it to even our first forth-rounder. There are too many teams sitting at the top of the 4th (Indy, Minnesota, and St. Louis could all use a receiver or two) that would jump on him if he were still on the board after Day 2. So unless you want to package picks this year (or include one from next year) to jump up to the first pick on Day 3, I think the Cowboys would have to pull the trigger in round 3, if they really want him.
This is the kind of move they like to make, considering they'd be getting a good value for a guy with a higher talent level coming off of an injury (see Chris Canty, Sean Lee, Bruce Carter, etc.). Also, note that, while Carter hasn't yet proven himself, those other two guys proved to be excellent value picks.
