Good trade. Third rounders are replaceable (I bet we get 1-2 at the deadline for Ceci and/or Blackwood), getting rid of Benning is addition by subtraction, and Liljegren adds a desperately needed puck-mover to allow Warf to break up the Ferraro-Rutta disaster and help out the forwards. He is probably the best option to QB the 2nd PP unit as well. Perhaps most importantly, just like with Ferraro/Ceci/Walman, he likely won't be here when the Sharks reach playoff contention status, so that doesn't matter (and his contract will be off the books). Was a 3rd round pick too much to give up given that Toronto was actively trying to dump him? Probably, but who cares...valuable addition.
