ND just wants him on campus. LSU started selling him on DT so they followed suit.
He's very athletic and could likely play OL or DL.
There's a current OL that redshirted this year - Sam Mustipher that his high school head coach was pretty adamant that his best position may be along the Dline. He apparently has a nasty streak as well. ND has options that they'd probably look at in the spring.
