Some other trivia, I think about these things so others might as well and enjoy the numbers:
Luka Garza has 819 points after two years. He seems a lock to go into the 1000 point club next year. If Cook, JBo, and Moss all return we would have four active members in the 1000 point club which I believe would be a first for the Iowa program. That also adds up to a lot of experience.
Rebounds - Can Cook make the Top 10? After three years he has 619 boards, 175 short of Reggie Evans at #10. So, he would stand a good chance of cracking into the Top 10. He's had over 200 rebounds each of the last two years.
Free throws - Cook has 324, JBo 214. Adam Haluska sits at #10 with 384 so Cook would have a good shot but Jbo not likely. JBo's three year totals are 47, 75, and 102 this year so for as great a free throw shooter as he is, he doesn't go to the line that often, mainly at the end of games when they want the ball in his hands so he will get fouled.
