The clock is ticking this week for the rookie class of the Cleveland Browns.
New head coach Eric Mangini wants to work with his first-year players as soon as possible. So Cleveland's rookies will be among the first groups called to report to training camp this Friday.
The problem is, as of Monday, the Browns still have four first-day picks who remain unsigned. This includes first-round center Alex Mack, second-round linebacker David Veikune and receivers Brian Robiskie and Mohamed Massaquoi.
Will they all have deals in place by the end of the week?
Whether reporting to camp by July 24 counts as a rookie holdout is debatable. The full team is mandated to report on Aug. 1, which is often viewed as a firmer deadline.
But what is not debatable is Mangini, a stern disciplinarian, is ready to get to work and certainly doesn't want the business side getting in the way.
