Why would he come to the NBA if he's just gonna get the veteran minimum? If he's as good as people say he is, he can get that kind of money in Europe. For reference, Mirza Teletovic is making 3 million a year on the Nets.
As for "no upside," well, he's already 25 and has probably been playing professionally since he was 16 or 17, like most Euro guys. I'm sure he's a nice player, but is he that much better than Rudy Fernandez or Andres Nocioni? Italy isn't even the most competitive league in Europe.
