Burke played Jyle Hogan in Season 1 of "Blue Bloods," and only appeared in three episodes. Hogan was an NYPD chief who frequently had dealings with Frank Reagan (Tom Selleck), though we rarely see him outside of board meetings. Being a perpetual guest actor, the three-episode stint Burke had on "Blue Bloods" is nothing he hadn't seen before – but for an actor like him to be relegated to more of a background character is arguably an injustice to his talent.
Even outside the notable authority figure roles he's been playing for 40+ years, Burke has proven his range in his beloved performances on shows like "Gossip Girl" and "Rescue Me," wherein he plays a real estate mogul and a priest, respectively. And yet, for his short time in "Blue Bloods," he has almost no agency as a character and seems to only serve the purpose of delivering exposition for Frank and the rest of the Reagans to act upon.
It's a bizarre choice for an actor known mainly for his talent at portraying law enforcement officials, as even in his small amount of screen time, he seems to be less of a guest star and more of a featured extra. Perhaps that's why so many fans may have missed his appearance in that 1st season of "Blue Bloods."
