I don't think Shattenkirk will be out more than 1 game (IF that). But, after seeing Parayko play with such poise under duress, I think he could handle the pressure and play well. His skating, hockey sense and shot are so good. He's big, and yet mobile.
He's clearly already by FAR the 4th best defenceman on The Blues. They need to get him used to playing on the left side, and into The Top 4 on the 2nd pairing as soon as possible, so he'll be perfectly comfortable there during the playoff stretch and the playoffs.
Easy on the predictions Robb. You did say last game you highly doubted Fabbri had a concussion
