I respect your ideas Easton, but here is my counter argument.
If we put Langs on Waivers, does anyone claim him? I don't think so. Maybe the Oilers, just b/c there like the Blues of 3-4 years ago and might want some veteran depth.
Porter and Cracken will do just as much, if not more then Langs. I'm glad he knows angles, but I don't think he has the foot speed to get there anymore.
We have enough veteran leaders in Jackman, Redden, Nichol, Backes. Do we really need to pay a guy 1.5 million to be a "leader"?
I didn't see any evidence of him missing angles in the (admittedly) small sample size of ice time he's had this season, and his angles were very good last season.
I agree that he's lost footspeed, so the tradeoff with him is that you lose some aggressiveness on the forecheck as a result (since he wouldn't have the speed to be a factor in transition defense if he didn't keep himself on the defensive side of the puck). The flip side is that you can always trust him to be where he needs to be against teams that are dangerous in transition. I think it's fair to say that Hitchcock values that pretty highly, given the system he's installed here.
Now, there's only so many teams that play that style of hockey. Obviously, places like Edmonton and Colorado would be a terrible fits for Langenbrunner given the coaching philosophies in place there, and there's zero chance he would be claimed by them. It's entirely possible that no team would claim him, but his value to
this team isn't inherently tied to how he's valued by other teams.
In a game against arguably the top team in the league in transition attack, a game where the Blues gave up numerous odd-man rushes and prime scoring chances due to poor positioning and poor puck management, I can't remember a single time when the 4th line was exploited or exposed by the other team. That doesn't seem to hold much value around here, but I'm willing to bet that Hitchcock noticed and appreciated that.
Now I'm not arguing that Langenbrunner should be a full-time player. I just think there's reason to believe that the Blues value him more highly than Porter at this time. I also think that the Blues brass probably disagrees with those who think that "energy" is all that matters (or is the prime consideration) when it comes to depth players.
This whole conversation stemmed from the loss in Chicago, as if Langenbrunner's play (relative to Reaves' presumed contributions) was somehow a significant contributing factor to that result. I don't see it.
