Trying a new strategy - opinions on this mock?

The new thing in drafting seems to be taking QBs and TEs sooner and waiting on WRs and particularly RBs.

Here's my team with the round that I took each player:

QB: Aaron Rodgers (1) RB: Ahmad Bradshaw (4) RB: Reggie Bush (5) RB/WR: DeMaryius Thomas (6) WR: Wes Welker (3) WR: Antonio Brown (7) TE: Jason Witten (2) Bench: Santonio Holmes, Stevan Ridley, Mark Ingram

I think I took Witten way too high. I think my RBs are decent and feel good about the WRs.
