For me, there isn't enough data yet to show the long-term effects yet. There is no doubt it can be a one or two year fix, but are you sacrificing years 3, 4 and 5?
My gut tells me that to have success year in and year out, you have to have significant continuity, and then fill in where there are weaknesses.
In ULM's case, there are a lot of weaknesses to address, so might be a good one year fix, I just don't see building a consistent program this way.
