NFL Head Coaches are limited to only two challenges per game, and receive a third if the first two challenges were successful. Because of the lack of challenges allowed per game they are hesitant when they should throw the flag. The front offices should be the same way when players have character issues. A red flag is usually thrown when a prospect does something questionable that could relate to academics, substance abuse, criminal activity, violations, and personal issues. But maybe they shouldn't be so quick to judge these NFL prospects. What if they were falsely accused? Are there really any character concerns?
