I think there were definitely more people who wanted this pick to roll over last season, but there were a number of us who wanted this pick to convey last year. Nobody was on an island saying it was better to get the pick now.
And while it's interesting that Memphis was clearly attempting to tank as recently as a month ago, with Morant being this good so soon and the fact they have a lot of good young talent up and down the roster, they may be going for it now. The bottom of the west is weak this season, and a sub .500 record will probably make the playoffs. Memphis just beat the two teams they're fighting with for the 8th spot (MIN/SAS) and clearly looked like the more talented team.
Memphis may still end up tanking for their pick, but if they do, as I've said before, nobody should be expecting this pick to yield anything great if it defers to next year.
