Reserve/Did Not Report LIST
This is a pretty straightforward list. A player is played on this list if he fails to report to training camp by the team-specified date. We know that
Randy Gregory did not report to camp because he's entered a drug rehab facility, we don't know exactly why Rolando McClain didn't show up.
Teams have fairly draconian measures at their disposal to deal with such no-shows, though they seldom use them to their full extent. Here's former player agent Joel Corry of CBSSports explaining
the fines that can be levied at a player on this list.
A team can fine a player a maximum of $30,000 for each day of training camp he misses. A player who signed his contract as an unrestricted free agent can be fined one week's base salary (1/17 of salary) for each preseason game missed in addition to the $30,000 per day.
A team can also recover a portion of a player's signing bonus. Fifteen percent of the prorated amount of signing bonus can be recouped on the sixth day of a training camp holdout. It's one percent for each additional missed day with a maximum of 25 percent of the prorated amount during training camp. An additional 25 percent can be recovered with the first missed regular season game. After four missed weeks, a team can recover 1/17 of the prorated amount for each additional week of the player's absence. The maximum a team can recover in a season is the entire prorated amount of the player's signing bonus in that contract year.
As a team, there's no point in resorting to such heavy-handed tactics if you still want the player to play for you, but if a team is looking to get rid of a player anyway, this might be one way to recoup whatever is left to recoup from that player's contract.
Players on this list do not count towards any of the 90-, 75- or 53-man roster limits.
