What about ISU's history says that a 7-5 coach isn't the best coach we've had? Also, 7-5 is an exaggeration. He's won 7 once. Every other time after that first season has 8+ wins. Also, beaten 4 top ten teams, which is more than the rest of his predecessors combined. More weeks in the top 25 too.
Don't be an idiot and pretend Campbell isn't the best we've ever had. If he stays, we'll have more years where we have a great chance to win 10+ games. Recruiting classes have improved, and when the ceiling is 7 wins, then the sky's the limit. It's the Wisconsin basketball model.
I was born in 1986... do you know how many 7 or more win seasons we've had between when I was born and Matt Campbell? A whopping 5. Since he's gotten here, if we include this year, it will also be 5. So in 6 years, he's matched as many 7+ win seasons as we've have in the last THIRTY FIVE YEARS. Get over yourself, and appreciate Matt's excellence.
