This might not be a popular opinion, but for the Flames it’s Giordano.
This isn’t a knock on him—he’s one of my favorite players—but he fits the definition of overrated. He’s revered like Iginla, but he never reached that level or consistency.
Gio hit a very late prime, which influences people’s memory of him, especially among younger fans. The reality is that, for the first eight seasons of his career, up until he was 31, he was a fully replaceable top-four defenseman, and Flames fans often discussed trading him.
At 31, he turned it on and became a Norris-level defenseman, but it’s important to remember that, out of the 15 seasons he played in Calgary, he would only have been considered a #1 defenseman for five of them. Even during his late prime, his level of play fluctuated—he’d have a Norris-worthy year followed by an average season.
He never had any playoff success and had more than a few instances where he crumbled under pressure.
