Harvey and Wheeler will be solid pitchers by 2015.
Niese will hopefully be pitching as good as he did in 2012.
Dickey has mastered the Knuckleball, and should pitch at least as good as he did in 2011.
Thats 4 Very Good Starters, with the potential of Amazing starters.
You add a couple hitters the next couple offseasons, the Mets could be Very Good in 2015.
