Purdue’s rushing defense has improved from last year, but the Boilermakers still give up the Big Ten’s eleventh most rushing yards. The Wisconsin Badgers host Purdue Saturday, and they’ll face a defense that has given up 151 yards a game on the ground — much fewer than last year, when the Boilermakers gave up 238 rushing yards each week. Also, new coach Jeff Brohm has made it a priority to get opposing offenses off the field quickly — as the Purdue “D” forces the nation’s 20th best percentage by three and outs, 20 of 50 in that department. Badgers’ offensive coordinator Joe Rudolph will deal with a Purdue front seven that has five seniors, and Rudolph says he’s impressed with their talent and depth. The unbeaten and seventh ranked Badgers will play a Purdue team that’s 1-1 in the Big Ten and 3-2 overall.
