I'll be "that guy" and say I don't like it. While it is possible that Ritchie finds a new gear offensively playing in our top six, he's also almost 26 and by that age, most players are done developing. If he doesn't find a new offensive game, then we've spent our last chunk of cap space (+1 extra year) on another 3rd liner and possibly one that becomes a drag in the top six.
IMHO our top need this off-season, besides a goaltender, was a genuine secondary scoring option to replace Hyman and Dubas didn't get that. So I'm disappointed and not particularly optimistic for September; I hope I'm wrong. (I also predict many who love this signing based on a mistaken caricature of who Ritchie is will start to turn on him by next April. Again, I hope I'm wrong, but there is a reason that neither Bruins nor Ducks fans liked him as a player).
