We have seen one major signing thus far today, as Michael Johnson and the Bengals agreed to reunite. As we wait for more free agent dominoes to fall, let’s take a look at a few more notes from around the league:

• Justin Rogers of MLive.com looks at how the Lions might work out an extension for newly-acquired DT Haloti Ngata. It is still unclear whether Detroit will even approach Ngata about an extension–the team may view him as a one-year stopgap, although the draft picks they sent to Baltimore suggest that is not the case–but Rogers believes a new three-year, $26MM deal might work well for both sides. Ngata himself said he believes he has three good years left, and such an extension would give Detroit a little more cap space for 2015 while creating manageable $7.5MM cap numbers in 2016 and 2017.
• Tony Grossi of ESPNCleveland.com says the Browns‘ strategy in attempting to re-sign Jordan Cameron did not make much sense. The Browns could have put the transition tag on Cameron for cheaper than the deal they offered, but they did not use the tag before the deadline and then made Cameron an offer for more than the tag value.
• Despite the team’s flurry of activity in the first week of free agency, the Rams have a few major holes to fill, and most of those holes are along the offensive line. As Jim Thomas of the St. Louis Post-Dispatch writes, the team has about $11MM in cap space, which should give them enough room to sign two out of the three of Stefen Wisniewski, Justin Blalock, and Joe Barksdale.
• Speaking of the Rams‘ offensive line, Nick Wagoner of ESPN.com writes that recently-released Jake Long could be back as the team’s right tackle on a shorter, cheaper deal, but that likely would not happen until after the draft. As far as the team’s quarterback situation is concerned, Wagoner believes all options in the draft–trade up, trade down, etc.–are on the table, despite the acquisition of Nick Foles.
• Matt Miller of Bleacher Report (via Twitter) lauds the 49ers‘ signing of Reggie Bush, who will pair with Carlos Hyde to create a strong 1-2 punch in the backfield. Miller adds that the team’s acquisitions in free agency will allow them to once again pursue the best player available in the draft rather than drafting for need.
• Mike Preston of the Baltimore Sun tweets that the Ravens had interest in Mike Wallace before he was traded to Minnesota. Baltimore thought that Miami might cut Wallace, thereby making him an unrestricted free agent.
• There is no new deal in place between the Saints and Keenan Lewis, but Mike Triplett of ESPN.com tweets that Lewis feels better about his long-term security with the club after meeting with unspecified team officials this week.
• While they will not receive any compensatory picks in this year’s draft, Mike Rodak of ESPN.com points out that the Bills are in line for multiple compensatory selections next year.
