I think you are under-estimating Smith though. Detroit is in shambles. This guy should flourish here. I don't trust Klein or Staal to stay healthy and putting Clendening out there vs. Pitt, Wash or Columbus is death because he's atrocious defensively.
McDonagh-Smith
Skei-Holden
Staal-Klein\Girardi
I think the plan here is to severely limit the minutes of Staal, Klein and Girardi down the stretch.
Personally, I would like to see Gorton have a heart to heart with Staal. "Marc, love what you have done but you are risking turning your brain into scrambled eggs with the concussion issue. Hang them up, protect your future and thanks for your service." If he takes that road great, if not try to move him for whatever we can get. Cut bait and bit the bullet. Then buyout Girardi and move Klein this summer. They are replace with Shatty, resign Smith and bring up Graves. McD, Shatty, Skjei, Holden, Smith and Graves. Lot's of flexibility for AV to play with and a very solid D corps.
