Gudas is actually a ****ing fantastic defenseman. I'd take him on the Rangers in a second over Smith..
He's absolutely a #2 defenseman on just about any team in the league, AND he is right handed. Bieksa went for a 2nd round pick at the draft 2 years ago... Gudas would easily be worth a low 2nd (30-40th pick) and an upper tier prospect--AT THE LEAST.
That said, there's no way philly moves him... There would have to be a large overpayment offered--by large, I mean a 1st and an NHL-ready prospect... No way a team trades that for 2 years of Gudas, no matter the cap hit. Even then, he's probably worth more to the flyers than those assets would be anyway unless that Asset was something like Sheary or Guentzel
