Seeing as Brendan is almost a Ranger again, I think that players like Prucha, Sjostrom and Fritsche are the odd men out. NY needs the cap space and it would give Prucha a chance to play quality minutes.
How about :
White and a fourth
Prucha, and one of Sjostrom or Fritsche.
no chance in hell dude
White and a 4th for Prucha is realistic......the others are going no where
