Something to think about when talking about the team's future

I brought this point up in the recap or postgame for NOLA, and I think its an interesting way to look at the 'we need Melo, we need role players, we need cheese' debate. Currently the Knicks are 11-9 but we have started playing like a team that is better than this record. If we played the way we have been playing recently for all 20 games we could have been say, 15-5?

The question then is: If this team is a 55 win team as constructed, do we want to add Melo to shore up scoring, or role players to shore up our most vulnerable positions: big man and backup point?

I really don't have an answer and think we need to see this team play at least twenty more games to figure this out, but I'd like to know what you guys think.
