The New England Patriots haven't expressed much interest in signing Cam Newton and that hasn't changed recently. According to NFL Media's Mike Giardi, the Patriots currently don't have any interest in signing Newton this offseason.
The keyword in that previous sentence is ‘currently', as New England could revisit the idea of adding Newton in the future. As of right now, it's understandable that there's no interest due to the unusual circumstances of the offseason.
With the coronavirus pandemic affecting the NFL, some free agents haven't been able to conduct proper physicals with teams. In addition, those same players aren't able to even visit with a team in person.
Given that, Newton — who is coming off of a season-ending foot injury — hasn't gotten a chance to meet with any teams yet. Of course, that could be subject to change once the NFL completely reopens team facilities. At the least, on May 19, the NFL is going to allow teams to partially reopen team facilities.
Since Tom Brady left in free agency, the Patriots have shown that they are confident in starting Jarrett Stidham. Though, they've been linked to Newton since he was released by the Carolina Panthers earlier this offseason.
Throughout the offseason, New England hasn't signed one of the marquee names that were available. Nor did they draft someone that could threaten Stidham.
If Newton proves that he's healthy, he would be a definite upgrade over what New England currently has. While Newton continues to recover from foot surgery, the Patriots seem to be content with who they have on the roster right now.
