If people wanna discuss it that's their decision, my only issue is that it's far too early to rate Armstrong for any of this. How do we know Faulk won't continue to play like a #1 and be worth his contract in the end, or that Petro won't live up to his contract in Vegas. Heck, the Blues might get healthy and make another run this year. Nobody knows what will happen, so I feel like we're just going in circles in terms of what there is to discuss. Time will tell if Army made the right call, but it will likely take years to know for sure.
And we can say the Blues walked away from Petro but he also walked away from the team. I don't think he was 100% committed to coming back and he wanted to get as much money as he could. Nothing wrong with that, but I blame both sides equally. They each had a line they weren't willing to cross. Petro could have gone the MacKinnon route to help keep the band together but he wanted to cash in. Good for him. I think the signing bonus money + being a big fish in Vegas with no state tax was enough to lure him away from St. Louis. People act like it was 100% Army's decision to let him go, but I don't see it that way. Loyalty goes both ways.
Agree completely that the book on this is far from written, and that any discussion about Armstrong should be taking into account far more than this one isolated (and incomplete) issue. Also agree completely that both sides walked away from each other.
As an aside, I personally don't believe that the ends necessarily justify the means in terms of process validation. Good processes sometimes yield bad results, and bad processes sometimes yield good results, so I think it's worth looking at things early on to try to analyze the quality of the process before the results come in and bias the analysis with hindsight. (It's worth looking at results, too, but they should add context...not blind validation.)
Take the ROR trade for example. We don't need to know how that story ends to say that the move was a good one to make. We moved two cap dumps, a project prospect, and two picks for a #1 center with term. ROR could destroy both his knees tomorrow and end his career, and Thompson could turn it around and become a top 6 player, and I'd still call that a good trade that Armstrong should make 100% of the time the opportunity arises. Three years of Schenn for Lehtera and two picks was a no-brainer as well.
This particular situation isn't anywhere near as clear-cut as those are, which I think is one reason why the resulting opinions are a lot more diverse.
