Complaining about Bennett undermines your credibility in a huge way with this argument. Bennett cost us no assets to acquire. His contract was below a million, which means it as 100% able to be buried in the AHL. When he was in the AHL, which he was most the season, he cost us $0 against the cap. He was with the team for 10 games (played 6, pressbox for 4). Cap is calculated per day but not per game, but let's assume he was up for the same percentage of days as games. That's 12% of the season. So he cost a whopping 78,000 against the cap. 80k is not the difference between a top 6 and a bottom 6 player. Its nothing really. Even if it mattered, we could have just had him in the AHL all year if we had someone better.
Not understanding the impact of his contract on our cap, to the point where you have complained about it multiple times, makes me doubt you know what you are talking about. Without reading anything else you have to say or really following the thread of this argument, I already side against you. I did read the rest though and your entire argument is flawed. But complaining about the cap implications is mind-bogglingly irrational.
You are using this past season's stats for Hall to bash Armstrong for a decision he made years ago. How was he supposed to know in 2 years Hall would have an MVP season and Parayko would stagnate. This is even assuming that deal was on even an option, which we don't know. Pretending it was, nobody would have predicted that then. Before this year, Hall was a pretty regular 60-point player with 1 outlier season. He put a lot of work this off-season to elevate his game working with some other superstars. Parayko's skill set had lots of people drooling with his top-pairing potential.
Also, your argument is a non-sequitur. It doesn't track as the two parts are unrelated. The decision not to offer Parayko for Hall was totally unrelated to the other decisions. Armstrong decided Parayko was more valuable than Hall in a vacuum. After that decision, he filled the roster out. But he didn't say, I don't want to trade for Hall because we need $650k to sign Beau Bennett. So why even bring up Bennett?
Now you are entitled to your opinion, but what's the point of posting it if not to discuss with others? I am no fan of Armstrong. There is plenty to take him to task for. I just have no idea why you are choosing these particular moves
