Not to degrade the article in any way, but it really doesn't really have much relevance. What the article tells you is that there are no 5 star players on either team, no one-and-doners, and the 3 and 4 stars just tell you that these guys have potential. Usually from year to year, beyond the first 10 kids in a recruiting class it is a crap shoot as to how they develop, and this is true at any stage. If the prognosticators were so good wouldn't they be able to evaluate the NBA draft classes much better, especially when the fish bowl is so much smaller? But it is the same way, beyond the first 3-5 picks there are busts, there are hall of famers and everywhere in between. So how can you evaluate a bunch of high school kids that aren't elite? Its just a guess.
What I see as the difference between Purdue and Iowa is that Purdue was able to do a little better job on assembling complimentary talent. Edwards is both quick and can shoot, a deadly combination. He is a volume scorer but he knows his role in that he has to shoot a lot in order to free everyone else up. He can get in the paint and shoot threes. When Edwards is being focused on, Cline can shoot. He can spot up or shoot off the dribble. Not terribly athletic but he is a great compliment to Edwards because you cant cheat off either one. In their 3 guard lineup, Eastern is their lockdown defender and will always take the other teams best guard option. He doesn't shoot many threes, but he can drive, has a midrange game, and is incredibly versatile in any lineup. Haarms gives them rim protection and some interior offense to make the other teams honest and not play small. Eifert and Williams give them different looks at the 4 and are solid players. The unit puts a lot of pressure on teams because of their complete and complimentary talents. You can play them any way you want and they have a way of countering that. Play zone, they will shoot it and shoot it well. Man them up and Edwards will go to the rim and eat you alive.
Us? We sorely lack perimeter quickness and thus ball pressure on our guards shuts our offense down to a halt because we cant get to the rim. And defensively, we dont have a rim protector. A quick point guard that can penetrate and defend would give us a ton of versatility that we dont have right now. We all know this.
Lets see how this looks next year, because if Joe T can provide some quickness, toughness and defensive skills and Nunge can give us a stretch 5 look, and Cook comes back, we will be a much more complete team.
A team can get away with having a point guard that cant penetrate as long as their shooting guard can. Moss and Bohannon is a really bad combination of guards. The sum of them is considerably worse than the parts.
