Of all these Freddy is the biggest disappointment. He had decent expectations, prior D1 success, and the hope was that he would be a legit contributor. Every other JUCO Frank has recruited has been a later signee and really there was just hope they would provide some depth. And most of those guys are also bounce around transfers; played at some D1, didn't like it, may or may not have played at a JUCO, ended up at K-State. Awaji and Canada were guys who weren't highly recruited, went JUCO to get better offers, then we took a flier on them and neither really worked out. Lawrence and Watson are similar to these guys as well.
Really, Jones is probably one of Frank's top JUCO recruits and hopefully he can play. Though even he played at 2 different JUCOs, but he seems closer to your traditional JUCO type; likely a D1 player out of HS that didn't make grades and had to go JUCO. Most guys just take the prep route now, though the NCAA in theory has made that a bit more difficult.
But I agree, this recruiting route has not been a very productive one for Frank, but he doesn't seem to be going away from it. He's due for at least one of Jones, Lawrence, or Watson to work out.
