Again, moving Girardi doesn't have to constitute a rebuild.
Say you move him to Detroit, and while I think the "two 'A' prospects" is a bit extreme, I think you could get a very good prospect and 1st round pick. Perhaps more if the Rangers ate 50% salary which could be a huge value add, or if they ate a contract in the deal. The Wings have a couple RHD prospects I've been keeping an eye on, as I think Detroit could be a good landing spot for Girardi long-term. They want to win now, have a good shot of doing so and they're half a day's drive from Girardi's home town.
Ryan Sproul is a mobile, offensive minded defender who can absolutely hammer the puck. Reminds me of Cody Franson, but he looks better than Franson did at the same age. Especially in his own end. I think he's a guy who sticks with the big club in 2015. Not that far off.
Another is Alexei Marchenko. He's a great skater who can rush the puck or make a fantastic break out pass. He's a shutdown, physical defender, but there looks like there is some offense blossoming in his game. I think he's bottom-pairing ready now, and could be a 2nd pairing guy next fall. Reminds me of Mikey Sauer with the way he plays.
Either would be a great add in addition to a 1st round pick, or if we're very lucky, a forward prospect like Tatar or Nyquist.
