I agree that proportionately Gilberto at striker is less problematic than our CB situation, DM situation, or whatever. But that being said, it's a very critical area of the team. Think of Vancouver trying to tough it out without a quality striker. With a great target man, they probably go from yo-yo bubble team to very solidly in the playoffs.
I'm not sure what kind of patience we'd have for these misses if the rest of the team was operating properly. We saw how that went early in the season and the same problems have popped up again later in the year, really only masked by everyone else's really poor play.
