I was at about 80% of Utah's practices in 2003 when Kyle Brady was a freshman. He worked out withe RBs, he worked out with the WRs, he spent zero time on defense.
It was apparent to everyone, including him, that defense was his future.
Kruger spent less time as a QB, but it's hard to argue with the results. Chris Kemoeatu was on the DL, now is with the Steelers at LG.
Morgan Scalley spent two and a half years at RB and WR. RJ Stanford spent his whole FR year as a RB.
You have zero credibility on the subject.
