Well there's the problem right there. Agents and people outside of the Saints organization don't have a lot of inside information on what's going on with the team.
The agents only know what they're told by the team when having discussions regarding their client. The team-agent relationship dynamic keeps either side from giving full disclosure. I'm not saying they are lying to each other. I'm saying neither one is going to show all their cards to the other.
The same goes with people outside of the Saints organization. The Saints may share some information with them, but it's the equivalent of showing them just one card from the deck of 52. Anyone outside the Saints is engaged in a lot more unreliable tea leaves reading than they are passing on complete information.
Individual players and people in the scouting department have compartmentalized information, they don't have all the information. I doubt that Ireland is sharing info and if he is, it's very unlikely it's complete information. The same is true for all of the top level management.
The Saints are one of the most tight lipped teams. Players and low level staff are probably occasionally sharing some tidbits of information they are getting, but none of them have a full view of the big picture.
The telephone game dynamic also happens. Player or scout hears something. They interpret what they hear and share their interpretation with Underhill and Triplett. Underhill and Triplett then interpret what they heard the other person interpret and speculate based on their interpretation of an interpretation.
That's not reliable reporting. That's why real reporting involves having multiple corroborating sources on every piece of information. The audience demands information at too fast of pace to allow for that corroboration. If Underhill, Triplet or any of the other internet people tried to take the time to corroborate information, they would constantly be posting "old news" and they would lose their viewers and their income.
That's actually exactly what you are doing.
Multiple "journalist" repeating something they heard from other "journalists" is not the same as a journalist having multiple sources that corroborate their information. You are believing hearsay and gossip, not journalism.
The information you choose to believe is not coming from a journalist who corrobrated their information with multiple sources (other "journalist" repeating the same thing is not mulitple sources.)
