I like Aranda and would prefer him to Diaz, but the money he got at LSU is a huge overpay IMO. Here are his results at Wisconsin. Basically the teams that should score points, did against his defense. He has gotten away without playing Michigan and Michigan State all three years. Only played PSU and OSU once each in the regular season. They got destroyed by OSU in the Big 10 championship game once as well. Those are the 4 most talented teams in the Big 10. That is Wisconsin's measuring stick, not Purdue, Rutgers, Indiana. Also, has not done well against the SEC. SEC teams are averaged 32 points and 435 yards in the 4 games. SEC teams ran for a lot of yds vs his scheme. Again, he's good but not elite IMO.
