And the Saints could pick them. By re-signing Young, they don't have to pick one in the draft if they aren't one of the best available players when the Saints are up to pick.
This is what the Saints shoot for every year. They try to build a starting roster they are comfortable with before the draft. That way they can pick the best players instead of being forced to draft someone to fill a hole in the roster.
I like their philosophy and approach on the draft.
