In a conference call with season ticket holders, Baltimore Ravens owner Steve Bisciotti said that while the team only had around $3 million in salary cap space, they were still looking for quality players, specifically mentioning offensive line as a position of need. Of course, once they end up signing DT Haloti Ngata to a more cap-friendly long term deal, it should free up additional space under the cap that could be used to help elsewhere.
In a story on Pro Football Talk, Bisciotti hinted that the team may be waiting for teams to trim their rosters down to 75 players, which they must do by the end of the month. In addition, if a player is signed before the regular season begins, and plays the first game, then they are due their entire 2011 salary, regardless if they are cut anytime after the first game.
However, if a player is signed after the first game, they are only guaranteed to be paid for the number of games they play for that team. This means if the Ravens sign a center, for example, to cover for Matt Birk, they would have to pay him for the entire season if he is on the team for the Septembver 11th regular season opener against the Pittsburgh Steelers. If they wait until after that game, they would only have to pay him until Birk was healthy enough to return and then release him, therefore only owing him the pro-rated amount for the number of games he was on the team's roster.
