So... how is the "elite point guard who can penetrate into the lane" what we're missing?
What we are missing is: Defense, defensive rebounding, and not turning the ball over leading to easy points at the other end (i.e., ball security). Iowa has given up at least 70 points in each game that they have lost. Their record in these games is 8-13. In games that Iowa has given up less than 70? 8-0.
Cook's game today was an encouraging sign in terms of defensive rebounding, and I see both Kriener and Garza being solid on the defensive glass as well. The defense has gotten progressively better as the year has gone on, and I see that trend continuing as the players continue to adjust to D1 ball.
