Tocchet is my favorite Flyer player of all time, but as a head coach he has been pretty abysmal. Even as an assistant coach, he has struggled outside of two years in Pittsburgh when they won the Cup.
He has bounced around quite a bit with gaps in the resume - Colorado, Phoenix, gap pleading guilty to gambling charges, reinstated by the NHL, TB assistant, TB head coach for 1 year, gap, Pittsburgh assistant, won two Cups, Arizona head coach for 3 years, let go at end of the 2020-21 season.
I've never got a sense of his coaching philosophy or expectations for his players. I think he is seen as more of a player coach. It would be a typical Flyers move to hire Tocchet, bringing a fan favorite back like they did with Barber, but I do not think it would work. Fletcher is likely out soon if the team does not turn it around significantly and so we'd again have a head coach working under a new GM they did not hire. They probably should have grabbed Sutter before he went to Calgary, but they may have thought he was too much like Vigneault.
