SB Nation's Pats Pulpit called it when they wrote that the workout "could turn out to be nothing more than Belichickian due diligence."
Teams often work players out to get a gauge of where they stand physically in case of injuries to other players currently on the roster. That's likely the situation with Burress, who remains without a team for the 2012 season. Burress, 35, was somewhat productive last season with 45 receptions for 612 yards and eight touchdowns.
At this point, though, it's a little concerning he's not even on a team. Perhaps he lands somewhere if and when another team suffers injuries, but it's hard to think he'd be any better in 2012 than 2011 without a training camp.
