Look I love Monahan, he is a great person and a leader. But if you think you have even an ounce of a chance getting past Vegas with him as your 2C you are certifiably insane. Monahan is not the player he once was, he can still sit in the slot and raise the puck exceptionally well over goalies pads, he can still win faceoffs. But that's about it, he's a passenger player at the end of the day.
Considering Aho got 9.5M for pretty much the same or less production and similar level of 2-way play over the previous few seasons I don't think 9M was at all an unrealistic ask in negotiations prior to the season. Players always start high in negotiations while teams always start low, then they tend to mean in the middle
