It's not just Monroe's homerism which, yes, is bad. But even worse to me is his whole I'm-still-in-the-game schtick: referring to The Guys by their cutesy-poo clubhouse nicknames; acting as a cheerleader and an apologist for The Guys; leaning hard on jock-talk crutches; and, of course, his general lack of actual insight for which he's apparently relying on his memory of what it was like when he was a player on the inside, rather than studying up on the game as an informed outsider.
In other words, he comes off like a YouTube or TikTok amateur, not as a broadcast professional.
