Remarkably, Diaco has now coached at five schools in the last five seasons: UConn, Nebraska, Oklahoma, Louisiana Tech and Purdue.

It’s also been an era marred by turnover for the Boilermakers. Brohm’s replacement defensive coordinator will be his third in three seasons. Diaco replaced Nick Holt, who is now coaching in Italy.

Diaco’s defense started off well, but faltered down the stretch. Purdue gave up 37 points in back-to-back losses against Rutgers and Nebraska to end the season.

It didn’t help that start pass rusher George Karlaftis only played in two games this season, but still, the scheme wasn’t working for Diaco.

Purdue especially had trouble defending the pass this season, as it ranked No. 13 in the Big Ten in passing yards per game allowed.

The Boilermakers’ season is over pending a bowl invitation. They went 2-4 in the 2020 campaign.
