Dynasty trade

[TruNinerFan]

I give: S. Greene
I get: Tim hightower and 2 first round rookie picks next year

This is a TD heavy league, 1 pt every 25 yards rush/rec, NO PPR

Here is my current roster:
QB- Romo, M. Ryan, Alex Smith

RB- M. Lynch, M. Barber , Mendenhall, S. Green, Fred Jackson, G. Coffee, B. Scott, T. Choice

WR- Calvin Johnson, Roddy White, S. Moss, G. Olsen, J. Morgan, Heyward-Bey

K- Kaeding

D-Vikings and Packers

if I make this trade, I will have 4 first round picks next year, This is a 10 man league. Is next years rookie class strong? any advice is appreciated.
