I have to strain to read between the lines of what he said, but to me it seems like they are pretty high on Javtokas. He didn't give Scola or Mahinmi much props, but his one bold statement was saying that Javtokas has turned himself into a good player. But then he also went on to say that Javtokas has opportunities in Europe as well as in SA, so it's more of what we knew.
Every time I've heard the Spurs talk about Scola, they never seem too excited. Pop will talk about Javtokas and Mahinmi, but when asked about Scola in the NBA and not on the Spurs. Presti wouldn't even say that this is the year Scola will come to the big leagues.
About Mahinmi, Presti didn't say anything to make it seem like he'd be over this season. He stressed that the Spurs have to be patient, so I'm guessing that means another year or two.
