McLemore was rated higher (5th) than Smart (9th) in 1/2013 by Draft Express. Smart opted out of the draft in April. At the time Woj said Smart was projected to be top 5 in the draft.
Draft Express had McLemore ranked at #2 after Noel in 5/2013 for the first and only time. Noel was 1st or 2nd all year. McLemore was ranked 5th in Draft Express's final mock. Smart was not ranked. He was supposedly very high on ORL's radar according to various sources and they picked 2nd. Since he wasn't in the draft, we don't know how he would have fared in the try-out process.
SAC was happy to have McLemore fall to 7 in the draft. McLemore went on to struggle badly in the Vegas SL and was mentioned as one of the biggest disappointments there. He then had an awful 1st year and was in trade rumors by the trading deadline.
The selection of Stuakas seems to mean that SAC wants something better at the SG than what they had last year. Given how much they need a PG and PF, it was a surprise to most that they took Staukas over Payton or Vonleh. Unless they are planning to move Staukas in another deal, it's tough to see how this bodes well for McLemore though you would think they would have given him another year.
