Here's some numbers off the top of my head. I'd give you more but I'm driving right now.
Petras is a winner. He is one of only 9 QB's to have won 10 games in a season. The other 8 were NFL QB's. He has the chance to become the only QB to have won 10 games twice. If it was not for COVID, he could have won 10 games that season (ended the year on a 6 game winning streak). Greatest QB? No. No question. It's Chuck Long who won an amazing 65% of his games while playing in the Big 2 Little 8, just 2% behind Petras. Give Spencer the 3 games against crap teams we beat last year while he was hurt and he's up to 70%. To be fair to the others, I'll leave out the 5 games he missed due to COVID which would put him in 1st place of all Iowa QB's.
Of the QB's that have started for 3 seasons or more, Ricky Stanzi leads the way is ahead of him by 1%. I won't mention that "Rick 6" had weapons like Shonn Greene, Marcus Coker, The Paki Bomb, Marvin McNutt, Tony Moeaki, DJK, Keenan Davis, Colin Sandeman, Terry Strause, and 8 NFL OL to play with because that would seem like I'm trying to make excuses for why Rick 6, who threw 5 interceptions in one of his wins, is not as good as his record seems.
Petras has the chance to become the 1st Iowa QB to win 2 conference championships and could've won a 3rd had it not been for the 2020 season.
