While these two didn't go 1 and 11, the Pons twins(Chan and Corby) are my favorite NCAA brothers. Despite the fact that neither ever qualified for Kinney/Footlocker, they finished 18(Chan) and 29(Corby) in Bloomington in 1999. Chan did this while racing the last 5 miles with only one shoe. If he had kept both shoes on, I can say without doubt or further qualification that he would have finished in the top 10.
