that’s exactly the kind of thing I was thinking of (and that happens). No surprise he didn’t like Jellico!
He didn't like Jellico because Jellico was a control freak who didn't listen to his subordinates, even when they knew more about something than he did.
If Riker had wanted a lucrative command, he would have done his tour on the flagship, then taken his own command in "The Icarus Factor". Everything he did up to that episode was textbook career building, and if he'd followed it to it's natural conclusion, he'd have been wearing admiral braid by his 45th birthday. Passing up the command he was offered was his first career-damaging decision, and more would follow.
Again, while that was unrealistic, it gets a pass: it was the only way to keep a very solid cast together.
Ah, Janeway's clever ploy to keep Harry out of the center seat!
You do have to wonder what Janeway's true feelings about Harry were, don't you? Given that her decision not to promote him was devoid of logic, that leaves only her personal feelings.
