Given Pasta and Macs age i would have to think adding a guy like Robertson now while they are both still in their prime would be a pretty good move. Especially with this front office there is no guarantee they draft and develop any forward properly, however you know what you're getting with Robo (or Necas).
Maybe that forward at 7 is 3 years away from an impact. Do we want to waste 3 of our top players' prime while we wait?
Whereas if you get one of those two guys now you have a clearer picture of what we have and can move forward and build the team appropriately.
