Crabtree kind of goofs up when he fails to mention that Bulaga and Clayborn were both 4-star guys coming out of high school. Iowa has had a pretty strong pipeline into the Chicago suburbs and they've landed a lot of top-tier recruits from that area, so I don't know if the analysis holds all the way down.
Ferentz has found a number of kids from South Dakota (Greenway, Reiff, Clark) who he has developed into really good football players and one has to give credit to the coaching staff for that.
I do see some similarities to what Kill is trying to do, but the bottom line is you get a core of guys that you can keep in the program through their eligibility. In recent years, Iowa has had some early departures (for the draft, injuries, or assorted hi-jinks) and I think that shows in the bit of a trough they've experienced since their 11-2 season in 2009-10.
But this approach isn't a whole lot different than what Wisconsin established under Alvarez. Find line recruits on both sides of the ball with physical growth potential. Get them bigger and refine their technique. Sprinkle in top-tier guys at the skilled positions. You still need guys who can amp it up.
Iowa and Wisconsin have always brought the lumber. Physical football teams. One of Kill's goals appears to be to match that level of physicality and I think that's a quality the Gophers have lacked since Holtz's short tenure in the early-1980s. I think we can build on that.
I don't know about anyone else here (and I respect the heck out of Billy Beane), but I'm just so tired of the "Moneyball" comparisons for anything that appears to be even remotely unorthodox.
