I'm not particularly fond of the media, but I don't see where the reporter has done anything wrong here. The title of the report is accurate and not misleading in any way.
Read the quotes and TWill said “I don’t want to talk about that," when asked about Witten. And he said of Dez “I mean Dez is my dog,” and “It’s different because you just miss the different stuff that he brings to the table." Not exactly saying he misses Dez, but the inference is pretty obvious.
The problem on the Witten response is there's nothing to indicate why he doesn't want to talk about it so it leaves it up to the individual to make an assumption. That's on TWill because he said he didn't want to discuss it. There are several reason he might not want to talk about it, some positive and some negative.
The thread headline might be a little leading. It did have a ? at the end, but I think it would have been better to title it "Does TWill have a beef with Jason Witten"? Or better yet, "Why did TWill not want to talk about Witten"?
