Perhaps I'm just scarred by the Nishioka incident but it seems like most non-Ichiro Japanese imports hit .310-.330 and saw their avg's fall into the .260-.280's. Iwamura, Aoki, Fukudome, HMatsui, KMatsui, Iguchi, Johjima are the recent names that popped out to me. He still could be a solid player but I think you hope for a .275, 5 HR, 20 SB line if you draft him. I wouldn't want him as a starter.
Hyun-jin Rhu has solid potential from Korea but he looks a little pudgy like Irabu. I had no idea the Dodgers spent so much on him. They continue to spend like drunken sailors and have made the Yankees look like penny pinchers.
It might be a good idea to keep an eye on Daniel Alvarez or Almedys Dias from Cuba if they sign soon. They might be 23-24ish (Dias might be younger to avoid int'l cap limits) but would probably need at least half a season in the minors.
