Sampson was, as we all know, placed in the "Poor Timing" category:
JaKarr Sampson, St. John's -- He's a tremendous athlete, a high-character kid who had a nice season (12.8 ppg, 6.1 rpg). But the Red Storm weren't all that relevant, and he's caught in between positions. If Sampson came back and continued to work on his skill level, his stock could get to a point where someone might consider giving him guaranteed money. But right now, the chances are he winds up overseas.
