I really dont think away teams get a block of tickets except the very few behind their team bench.
Most really good B1g teams have sellouts so not much available to away teams.
In the last 40 years I usually only notice about the 30 seats behind the away teams bench having their fans.
Unless you have a deal like Lick where nobody would show up and the Wisky and Illini fans would show up in big numbers.
