Before going to Europe, Jennings was highly regarded as a stud PG.
He's too quick, jumps high enough, and had a better than average court vision with some creativity.
There was even a game where he played against O.J. Mayo where he still manage to get 24pts and 10 dimes while guarding Mayo most of the time. Mayo did get I think 28pts at that game but was on less than 30% FGs.
We'll Mayo is now in the NBA and we all know he is a stud.
Here's a good clip from this site:

where I can say you will have a better preview of the potential of this kid. Tried to search this in youtube but mostly found crap footage of him most of the time.
