You asked me about Davis, not Raveling. Do you want to discuss Davis or Raveling? Davis walked into a situation that most coaches dream about. And this is what he did with that:
Year School Record Big Ten Big Ten Standing Post Season
1986–87 - 30–5 - 14–4 3rd BIG -
NCAA Elite Eight
1987–88 - 24–10 - 12–6 - 3rd BIG -
NCAA Sweet Sixteen
1988–89 - 23–10 - 10–8 - 4th BIG -
NCAA Second Round
1989–90 - 12–16 - 4–14 - T–8th BIG
That's a meteoric crash in his first 4 years! He should have absolutely been fired after his 4th year. At any other respectable program, he's fired. That's garbage. It took him 9 more seasons to reach another Sweet 16 and he did it as a lame duck HC.
