Seriously, just look at the Best PFs that Iowa has had in the last 20 years.
Bowen, extremely good defender and decent offensive game. Role player in the NBA for a decent career.
Evans, double double machine for us. Role player in the NBA for a decent career.
Brunner, extremely gifted player scoring, rebounding, and defense for us with a lot of heart but only 5'10" tall. Not even a sniff in the NBA.
White, decent shooter, high motor, dunk machine for us. Barely got a sniff from the NBA.
What does Cook offer?
1. He's not an elite rebounder currently, and that is hard to teach as it typically comes naturally.
2. He's not an elite defender, which could be taught over time.
3. I've seen his height listed between 6'7" and 6'9". Typically the real answer is in the shorter end of the spectrum.
4. He has very good athleticism. But I'm not sure if he's at Thunder Doug's level of jumping.
5. He has shown some streaky ability to hit outside shots.
6. He's show some really great post moves which are hard to teach.
All of that adds up to a guy that is here for four years unless he develops a portion of his game up to elite level. Consider that only 60 people get drafted every year. Many of whom don't make a roster. Plus a large portion of that 60 are coming in from overseas. Plus there are a lot of great college players that never play in the NBA because of size or one hole in their game. Just for us I can count off Woolridge, Settles, Kingsbury, Recker, Brunner, Haluska, White, Uthoff, and others. Of course some of those guys were hurt by injuries but the point still stands. Around the time that the NBA started pulling in a lot of foreign players is when Iowa stopped routinely putting players on an NBA roster or at least 2nd round draft picks.
Someone mentioned McDermott made it so Cook should be able to. Well, Doug is an elite level shooter and decent enough at everything else.
Having said all of that. The early returns show that him being here for four years will be very good for us.
