I'm not saying this to mean that I think this is a good thing, but at this point in his career, I don't see Landon putting this team on his shoulders and saying "Let's go". Moreover, I don't think he can with this team.Landon as the "barometer" is a cop out. He's been playing too long with this team to keep pulling that crap. I don't expect it from Beckham and Keane because they'll always seem like hired guns to me. The G's are still Landon's team and he should act accordingly in tandem with Bruce.
I think Landon did do that with the team that won the Cup in '05, but that was in the pre-Sooper Club era, where all he had to do was gather the guys and play in spite of the Big Giant Head. Today's team has too many big voices and agendas, and I think Landon sees that and backs off. Note the way that Landon followed his brilliant leadership with the '05 Galaxy by embarrassing himself with the WC in Germany.
Landon will lead now when his leadership is the final thing needed for the team to succeed. It was easy at Everton because it was a team that just needed another piece. Landon provided that and everybody loved him.
And for Landon acting "in tandem" with Bruce, that ignores all of the other power centers on the team, ones that will not allow themselves to be ignored.
The problems are systemic. Beyond Landon's funk, look at what's happened with Sarvas. Whatever's wrong isn't going to be solved by Landon making more runs and shouting "Come on guys, let's go".
