MARCH 5, 6:05PM: Fowler continued with the updates today, tweeting that, while New Orleans and Carolina remain in the conversation for Carr, the former Raiders quarterback “has a slight lean toward the Jets.” It’s unclear what New York’s main priority is, as they’ve been heavily connected to Rodgers, but Fowler reports that they’ve “made an impression” on Carr.
MARCH 5, 3:36PM: While New Orleans remains one of the top teams to watch on the Carr front, ESPN’s Jeremy Fowler notes that “at least” two others have inquired about the four-time Pro Bowler. The Jets and Panthers are in a different situation than the Saints, of course, but that trio could see increased competition in the coming days if more teams join the fray.
MARCH 4: Plenty of attention around the NFL is currently being paid to the 2023 class of quarterbacks in the upcoming draft. The top veteran passer currently on the market is certainly the subject of significant speculation and reporting as well, though. 
Derek Carr has been connected to a number of teams since he was released by the Raiders. Those include the Jets, who view him as their backup plan to Aaron Rodgers, and the Saints, who are reportedly prepared to work out a deal with Carr at any time now. The Panthers could also be in the market for a veteran signal-caller, though they are positioned to be contenders for one of the top rookie QBs this year as well.
Carolina met Carr in person earlier this week at the combine. That signaled their interest in at least doing their due diligence at the position, though it also came not long after the team was reported to be unwilling to meet the $35MM-per-year contract the 31-year-old is said to be seeking. That did not represent the only contact between the Panthers and Carr.
The two parties spoke over the phone before the combine and will do so again this Monday, as detailed by ESPN’s David Newton. When speaking on the subject of a possible Carr deal, head coach Frank Reich indicated that he would view the four-time Pro Bowler has a long-term investment despite his age (especially compared to the possibility of drafting a signal-caller in the first round of April’s draft). The latter approach is nevertheless believed to be the Panthers’ preference, reports Cameron Wolfe of NFL Network (video link).
That could point Carr towards the Saints as his free agent process continues to take shape. On that point. Luke Johnson of the New Orleans Advocate tweets that Carr could sign with his new team before free agency begins, perhaps as early as this coming week. That sentiment is shared by Wolfe’s colleague Ian Rapoport (video link).
The Saints have plenty of work still to do in terms of becoming cap compliant, let alone carving out enough space to afford Carr on a market-value deal. Like the Panthers, however, they are in need of at least an intermediate-term upgrade under center, so their interest is unlikely to wane in the coming days. That timeline could see a final decision made on Carr’s part, which would represent the first major development in the 2023 quarterback market.
