Great question about going RB-RB or RB-WR.
In the same mock 34=sweetness is in, I do have the 4th pick.
Rd 1 - A. Green
Rd 2 - T. Owen
Why did TO fall all the way back? A couple reasons - but a lot of it had to do with guys desperate to fill that 2nd RB slot in a RB-RB strategy. The 2nd Rd went: F. Taylor, Holt, S. Davis, CPepp, Barlow, D. Davis, Dillon, R. Johnson, TO, Vick, Manning, McNair.
To me, I probably wont draft half of those RBs in the 2nd rd. I guess if a RB you are really big on falls into your lap in the 2nd rd, fine, but I will be looking for the elite WR or QB to fall into the mid to late 2nd rd if I have a pick in the top half of the first rd.
