What a silly discussion. The truth is its all potential at this point. Some 4 stars bust, and some 2 stars end up All Americans...like David Montgomery.
Iowa wanted Brock, pressured him to commit before he was ready and when he wouldn't they canceled his visit and went with Goodson. There's just not that much mystery here. From reports I'm hearing/reading, Brock has been an ISU lean for quite some time...though NW actually made a real run at him thanks to Ayeni.
How convenient for you we'll never know if Brock would have still chose ISU over Iowa or Notre Dame since he had an offer from neither on decision day. Have already heard clown fans say they got him over Iowa and ND...that's simply false!
