Could be a case of having a high return for Vrbata, and teams looking elsewhere.
With the exception of Vanek, each team that made a trade today got a physical player in return, as hbk noted. Maybe teams felt comfortable with their "skill" guys and the market dried up.
People get hung up on trades happening in a vacuum, but they don't. Returns are never going to be level when comparing one trade to another, and just b/c teams are talking doesn't mean that action takes place.
Of the list of teams, I would guess that at least one or two couldn't guarantee that they could make it work financially by taking on Vrbata's contract. This includes us getting a bad contract in return - maybe the draft pick offered wasn't sweet enough to take on a player with term remaining. Once you get past that, the teams that expressed interest in Vrbata found other deals.
