This isn't down on you specfiically because 95% of sports fan do it, but it bugs me how much people don't really read the specifics of these reports. It all just gets jumbled into a generic mish-mash.
The report you linked says that Adam Schefter reported that Tomlin "likes" Justin Fields. That is the entirety of the reporting that is done. Schefter then goes on to *speculate* that the Steelers might be interested in FIelds in a trade because they presumably need a QB and Tomlin likes Fields. At no point is it actually reported that the Steelers are interested in trading for Fields.
The link I posted directly states that the Pittsburgh front office is not interested in trading for a potential starting QB. That could be a lie by either the reporter or the front office, but it's not speculation, it's an actual report.
The two links don't contradict each other. It's perfectly possible that Tomlin likes Fields and the Steelers don't intend on trading for him.
The following are all different statements but people treat them as identical:
"Team X has a need at Player A's position, they could try to make a deal"
"Industry sources think Team X might explore a trade for player A, it seems like a good fit"
"Team X intends to upgrade at this position and Player A is on their radar"
"Team X is hoping to trade for Player A"
"Team X is in talks about trading for player A"
Those all mean completely different things, but sports fans treat them like they all mean the exact same thing. There's a certain amount of smokescreening going on in pro sports, but part of the reason it feels like reporters don't know anything is because people don't read what the reporters actaully write.
