As the OP of the poll…
the original poll question was posted immediately after the Michigan game last weekend. The question was “if you have to decide NOW, do you fire frost or bring him back for 2022?” There were over 1,000 votes. Around 85% voted to bring him back. This is where the 15% came from. Apparently dean referenced it in support of the staff this week, which I missed and was asking about in the OP here.
i posted another poll with the same question immediately after the game today and the result was around 75% fire. Much fewer responses, but still. Seems like today really sunk frosts support.
