It's one thing to wait until 2nd or 3rd round to get a Guard, but it's another thing when that Guard can be Larry Allen status. If he's a perennial probowler, then you get him in the first round. Emmitt Smith got most of his runs behind Larry Allen.
You would hope to trade down and get the same guy for a cheaper value and that is what we will try and do but you must also look at how important that player will be to the team and getting him would tremendously enhance our OL.
I agree with going with OL for both #1's unless a true game breaker is available on defense.
