A Philadelphia writer (forget who, not that even one of them is reliable) claimed there was a deal lined up to move Letang for Voracek AND Simmonds around the time of his contract extension.
Would have been a Hell of a trade, if true, (Kunitz-Crosby-Voracek, Simmonds-Malkin-Neal) but we'll never know if it was bull**** or not, unless Shero or Holmgren write a memoir someday (doubtful).
Never would happen now, but at the time, Letang was a Norris runner-up, Simmonds was a one-off overachiever, Voracek was perhaps perceived to be a leech and Schenn was supposed to be the next big thing (instead of the afterthought in a Richards for Simmonds deal, which is how that trade will be remembered), so it would have made at least a degree of sense for the Flyers. None of those perceptions really match two years out.
