The Nebraska football team that takes on Minnesota Saturday afternoon in Minneapolis will be in its best shape of the season, Husker head coach Bob Devaney admitted Thursday. "Our quarterbacks, Jerry Tagge and Van Brownson, appear to be 100 healthy now or close to it," he observed, "And Donnie McGhee (offensive guard) seems to be okay again." McGhee had been on the doubtful list all week because of leg and shoulder problems. ' However, we've got a lot of guys, who could be re-injured in a hard-hitting game," Devaney added, mentioning players such as Tagge (leg), Brownson (arm), McGhee (leg and shoulder) and split end Guy Ingles (ribs). A 51-man Husker traveling squad will leave at 1 p.m. today with a 3 p.m. workout scheduled in Minneapolis. They'll bunk at the Hotel Leamington a d return to Lincoln immediately after the game, due to arrive about 7 p.m. Fence Being Added In response to concern about
