If you got to choose two areas where Nebraska was an NFL factory at, which would you choose?

-Nebraska hasn’t been an NFL factory at any position for a long time, sadly, with limited draft picks over the past several years. Meanwhile, Iowa sends MANY players on the O-line, D-line, DBs, TEs, and Wisconsin sends OL, RB, LB and more to the league

-If you were to choose two positions where it was most important for Nebraska to develop NFL talent (and most importantly, all-B1G type talent), where would you choose on the roster? Are any spots likely to get to that spot in the near future or still lots to be determined and proven?
