No need to trade up, especially for only amedium value position.
If you look at JRs' drafts, he always looks at value at the spot. And if there's a good player, at a premium position (OT, DE, CB, WR)that drops to us, he'll take that player.
I also wouldn't discount the prospect of JR trading down if he gets the right offer. He likes having extra picks and we more guys to fill out the back end of our roster than we do immediate starters.
