Lack of Follow-Through Cited as Weakness in Villaraigosa's 1st Term

The LA Times today revealed a memo and information from sources about all the recent resignations and new hires within Mayor Antonio Villaraigosa's administration. The most poignant fact, one that most people are likely to agree with, is this: a lack of follow-through on certain policy goals.
This is one reason why Villaraigosa earned little respect as a leader during his first four years. He was really good at showing face at event after event, announcing and sharing new ideas, visions and goals, but the accomplishments were little and far between.
Recently, Villaraigosa moved one of his deputies to the Airport Department with a goal of getting a train to LAX. He also moved another of his deputies to the building and safety department in order to streamline the process a developer must go through to build a property. Others have resigned, like LADWP's David Nahai and the Community Redevelopment Agency's Cecilia Estolano, but the Times indicate these were not necessarily amicable moves.
Villaraigosa has 3 and half years left. Can he make these last few count?
