What should the New Jersey Nets do in the offseason?

They need a top 25 big man for that team to finally click. I think they get Carter and Jefferson to sign extensions for the next at least 3 years. I think they hold on to Jason Kidd for 1 more year and let get a young promising plater in exchange in the future. If Marcus Williams can get 1 more year in under Jason Kidd he could be a top 5 point guard in a couple years. Hes the future... build around him.
