So, if Iowa has had three black starters in the past 40 years, that's great and the tweet was off. BTW, who are they, for the record.
I just think using the race of starting QBs as a metric for this is stupid.
Pete Gales, Brad Banks, and Jason Manson. Manson wasn't a regular starter, but started a few games, so I included him since the data point was black QBs who've started more than one game.
