Something about Hamilton to Anaheim last off-season I think (could be wrong, if so I blame it on the beer)
Faulk to Anaheim for Kase was basically agreed to, Faulk blocked it with his NTC.
A few more Carolina ones.
Tomas Kaberle for Brassard early in 2012-13. Brass was on the outs in Columbus and Kaberle was a f***ing dumpster fire in Carolina. Can't remember why it was nixed, I think Kaberle may have had a partial NTC and didn't want to go to Columbus
Jack Johnson for the #2 pick in 2006. Sounded very close to happening and then the week of the draft Pittsburgh asked for Ladd as well. JR rightly told them to pound sand on that one.
Ray Whitney to LA at the deadline in 2010 for LAs first and one of Teubert or Voynov. Whitney blocked it with his NTC.
Mike Fisher to Carolina for Zach Boychuk and another piece (1st?) at the 2011 deadline. Trade wasn't nixed but Ottawa got an offer from his preferred destination in Nashville that was accepted instead
And the big one: Hall for Faulk in 2016... As Bob would say "it's one for one".
