Taliek had a few things going for him. His assist rate was very high (above guys like Kemba and Shabazz), he played very good defense (it might be somewhat of a stretch to say he took the other pg's jumper away, but I get your point) on a team with some suspect perimeter defenders, and he didn't turn the ball over.
Unfortunately for him that last part didn't always hold true in our biggest games, which complicates his legacy a bit. While his assist to turnover ratio was nearly 3 his senior year, he turned it over 19 times (including 7 in the one competitive game) against 33 assists in the '04 tournament.
To his defense, he can't be held responsible today for the ways in which the game has evolved since, and in a different universe where Marcus Williams is starting alongside Ben Gordon, we may have been more talented but not better. He was a winning player who did what we needed him to do, maybe not quite as good as a player like Aaron Craft but of that same mold.
