Understandably because Frost was a highly touted prospect when the Flyers drafted him 27th overall back in 2017. Frost had just 3 goals and 3 assists in his first 27 games this season, this caused Tortorella to called Frost a "Toilet".
Torts comments were obviously a little harsh, but Frost has used that as fuel to heat up. Since Tortorella's comments Frost has had 16 points in his last 16 games. Frost also had the best game of his career vs the Arizona Coyotes putting up a 4 point game.
