Joseph actually outscored Perron at even strength last year. Only reason Perron had more points last year is because he played almost 3 minutes a game on the top PP unit of Detroit, while Joseph only played 54 seconds a game on the second unit.
He won't get that here with Stutzle, Tkachuk, Norris, Batherson and Giroux in our top 6. Might push Greig out of the top 6, which I don't love and put up 40-50P because of it, but that doesn't mean he'll be more valuable than Joseph all-around.
Not sure why people are so hyperfocused on who Joseph's replacement is. We had room for a top 9 forward and we signed two. Could have just signed Amadio and rolled out an excellent shutdown line of Joseph-Pinto-Amadio, not to mention keeping the 3rd and having an extra 1M in cap space to help extend Pinto and maybe add some depth.
