Is the absence of star players at OTAs cause for concern for Cowboys?

The Dallas Cowboys concluded their second round of Organized Team Activities and, once again, the focus of the offseason training centered around who wasn't attending the workouts. For the second consecutive week, star wide receiver CeeDee Lamb and elite pass rusher Micah Parsons did not join the team for the training sessions. The All-Pro edge rusher was in Dallas briefly but left quickly after meeting with the team and doing some media work, but elected to do nothing on the field. This isn't likely what the organization had in mind when Parsons said he would be at OTAs.
