Yes, he has no official title with the Giants, but he has been right in the past. Apparently he was friends with some in Gettlemans circle. "Tim" announced Rhule isn't coming he is going to Carolina, before other media outlets.
He also swore the Giants would not pass on Andre Thomas if there when the Giants picked, this was when other sites had Becton or Wills as a favorite. Because of his friendships in the past he still has guys on other teams that he talks to. Real or not, it is fun to talk about...
As for the Rumor:
There are two:
One: the Patriots are enamored with Marvin Harrison Jr. and will take him with the 3rd overall pick and will offer Chicago 2nd rounds and some more picks in a package deal for Justin Fields.
Two: Washington is ready to take Joe Alt and will also offer a 2nd round and some more picks for Justin Fields.
If true, this would make one of the top 3 QBs available to the Giants
How does a guy that is in the "know" with Gettleman, have anything to do with the Commanders or patriots... lost me on that one, sounds like someone needed filler for a youtube video. Betting odds currently have the steelers and Falcons as the favorites for Fields.
