I played D-II in Minnesota.
I don't think a lot of talent that makes up the D-II squads is much of a threat to the walk on program at the "U". I played with two guys who eventually played in the NFL. The guys had both been on D-I programs. One left the "U" when Gutey took over for Holtz, he had hoped that Lou wanted him to follow, but he didn't. The other left wisconsin after arguing with Morten. Our All-American RB was considered too short to play in the Big Ten. The All-American DB was missed, because who recruits Greenway H.S. for football players? He played basketball instead of Hockey, so he was doublely cursed. The vast majority of the rest was made up of players from Northern Minnesota, Northern wisconsin, The 'burbs, and a few from father afield like Bozeman, Montana.
It ended up being a excellent team, who was passed over for Post Season Play because at the time we played in the old Northern Intercollegiate Conference. The D-I teams found the best players, mostly, and with the one exception did not miss out on good walk on candidates. The real losers in this would be a I-AA teams, that at the time, did not exist in this area. UNI was the only one of note, and neither transfer even considered going there. The was one other problem at the time, when Lou showed up, he sent walk-on letters to every High School Senior in Minnesota. It was impossible to tell who he really wanted, and who he was just being polite to. I got one from Gutey, but I was too slow to even think off walking on at the "U" since I barely played at UMD.
