They should all be the same from a recency point. More important, phone calls to a player are largely useless, except maybe to give you an idea if you are winning a battle. And there is generally no reason to battle in D3.
Check out the recruiting part of zhawks' pinned thread for a little early guidance. There is also a D3 recruiting thread by oldresorter somewhere that is a bit out of date (before potential and future stars) but probably still useful. It shoudl be in the useful info thread, otehrwise you can probably find it searching in the Tarkanian thread.
