Context is important with the Glazer quote. Look at the blurb via PFT again:
Both quotes "per Glazer", so how did Glazer get it? This wasn't a press conference, and he didn't have a one-on-one with McDaniels. Higher in the same article:
So McDaniels allegedly said it at a staff meeting. Since we can safely assume Glazer wasn't part of McDaniels' staff, that makes the claim double hearsay.
McDaniels denied the claim:
Whom should we believe? Glazer and his anonymous source, or McDaniels directly?
Notice that Mike Florio didn't have McDaniels' denial as part of its story. And of course now in all the retellings of the story - such as by that maniac Steelers fan who wrote the Spygate book - McDaniels' denial is nowhere to be found. People only repeat the story that supports their agenda.
