I've made several updates to the OP:
-I have added Matthew VandeBerg to the list.
-I updated recruiting rankings. Several Iowa commits, including Delano Hill, Nic Shimonek, and Trevon Young, have been upgraded by one service or another in the past month.
-Godwin Igwebuike, a RB/DB from Ohio, committed to Northwestern about 10 days ago.
The past month has been pretty quiet on the recruiting scene. Watch for things to pick up considerably with high school games starting (new film to be evaluated means new offers to give out) and official visits beginning in conjunction with the college season.
