Respectfully, strongly disagree. I won’t make the case though, just move on. It would be too easy.
Yes, but let's look at football... "Personal responsibility" doesn't just mean the players.
As university Presidents, every one of those Presidents is a steward of their entire university and their reputation. They had to make an individual/personal risk/reward decision about the value of sanctioning official football activities in a pandemic where their university could take an enormous reputational hit if they irresponsibly put people in danger. Their vote to cancel the fall football season occurred because more than less [12-2, if the reports are accurate] believed that the risk to the institutions were greater than the reward.
That's why I made the [relatively flippant] argument that if the players want to play football, go find an open intramural field, choose up teams, and play. The players have personal responsibility for their own actions.
But the university Presidents have a responsibility to not sanction activities which will bring shame and opprobrium upon the institution (or conference) as a whole.
So "let them play" is only one half of the decision. Every one of those players represents the name of the university on their uniform, and
there are other stakeholders in the decision of whether or not to have a fall football season. Those other stakeholders have a responsibility not just to the athletes, but to the institution.
