A position to draft that kills three birds with one stone

If… and this is a big if… but if the cowboys are setting at 19 and there isnt a top LB… Derwin James is long gone and the best player on their board is an offensive lineman that they believe can start at LT i say do it…

The first bird it kills is now you have five starters on the oline.
The second bird it kills is not having to find a quality starting LG bc collins moves over.
And the third bird it kills is that rookie who will start off at RT slides over to the left side if tyron gets hurt.

Just a thought… and i do have a player in mind… UCLA OT Kolton Miller.
