Ritchie would play minutes with the Anaheim Ducks starting in the 2015-16 season. And he would land a career-high in points during the 2018-19 season (31 points). Ritchie would prove to be a bit impulsive and sit in the penalty box for unnecessary plays, which Anaheim didn't like.
After that, the Anaheim Ducks would trade Ritchie to the Boston Bruins. In exchange, the Ducks would get forward Danton Heinen.
Ritchie's start with Boston would be disastrous. During the 2019-20 playoffs Ritchie would record 19 penalty minutes. Bruins fans even blamed Ritchie for their second-round exit to the Tampa Bay Lightning.
Ritchie's best statistical season of his career would be in 2020-21. He scored 26 points in 56 games while accumulating only 37 penalty minutes. Ritchie will become an RFA at the end of the 2020-21 season. Because the Bruins chose not to qualify or sign Ritchie, he became a free agent. Because he was on the Bruins' first power-play line, some say Ritchie had his best statistical season.
The Toronto Maple Leafs would sign Ritchie to a one-year contract. Ritchie's time in his hometown Toronto was short-lived. In 33 games, he recorded a whopping 9 points and had a -6 rating.He would then be moved to Arizona as the Leafs needed some cap relief. Currently, Ritchie has suited up for three games with the Yotes and has two points. Will Ritchie ever be 10th overall caliber?
