I'd rather have the financial flexibility going forward. If you're talking about finding someone to fill out the rotation for the rest of the year, sign Wandy Rodriguez to the minimum.
His minor league numbers were never very good.
Guy was/is/will continue to be a poor hitter and awful overall player. He lost any chance of value once he moved off of 3B.
In the first round, you're supposed to draft guys that could be stars.
Nola will never be a star.
Why waste the pick? You can get low ceiling college arms later in the draft.
