Yup. As a kid I had a coach who, on running plays, had the receivers (including the off side TE) "run 'em off." Their job was to run fly patterns and not engage to block until they were at least 10 yards downfield. Granted, at that skill level you didn't have the CBs & LBs reading and reacting like they do in the NFL, but it's do-able, especially against man coverage.
Running 'em off certainly must be better than expecting a WR to block one of the big boys, but like someone said above, they may have been showing that look to set something else up - if not in today's game, then maybe down the road (vs Jets?)?
