Something I just heard that I thought was interesting.
Perhaps Howson a year ago was more shrewd than we thought. People were chastising him for not making the move to trade Nash on trade deadline day because he ultimately settled for what was offered (or less than what was offered) anyways.
BUT there may have been a twist. It is possible the Rangers wanted to include their 2012 1st round pick as opposed to the 2013 1st round pick. Don't forget the Rangers were on their way to winning the President's trophy as the regular season leaders which meant their pick would be pretty high. Howson also negotiated LA's pick to be conditional on which one we wanted (last year's or this year's).
Perhaps Howson believed that this 2013 draft was deeper which is why he didn't do the trade a year ago.
