After a pair of tense contests, No. 12 Notre Dame will try to find its footing against visiting Purdue on Saturday at South Bend, Ind.Notre Dame (2-0) is coming off a 32-29 win at home against Toledo. The Fighting Irish trailed late in the fourth quarter but escaped with the victory after Jack Coan fired an 18-yard touchdown pass to Michael Mayer with 1:09 remaining.It was the second straight nail-biter for Notre Dame, which needed overtime to knock off Florida State in its season opener.”I obviously didn’t do a very good job preparing them,” Notre Dame head coach Brian Kelly said after the narrow victory over Toledo. “I thought (our team) played with more intensity in the second half, but sometimes you don’t want the circumstances to have to dictate that they have to play with more intensity.”Notre Dame’s next test will come against Purdue (2-0), which is coming off a 49-0 blowout win over Connecticut last week. The Boilermakers won their season opener 30-21 against Oregon State.In the latest win, Purdue quarterback Jack Plummer completed 16 of 20 passes for 245 yards and four touchdowns. He helped the Boilermakers build a 35-0 halftime lead.Purdue head coach Jeff Brohm expects a tough challenge as his team looks to improve to 3-0.”Notre Dame is a veteran football team,” Brohm said. “They’ve proven they can win at a high level. They play one of the toughest schedules in the country every year against great competition. …”They’ve had to work for the last two wins, which actually from their standpoint really is a good thing because it gives them a chance to see the few things they need to work on to get better, but they found a way to win. That’s what winning football teams do.”Coan leads Notre Dame’s attack on offense. He has thrown for six touchdowns and two interceptions while averaging 302.5 passing yards per game.
