“BYU quarterback Zach Wilson, widely projected as the second overall pick in next month’s NFL draft.”
Also noteworthy: “During Wilson’s workout, news broke that the 49ers traded up with the Miami Dolphins.”
So, the trade was done before the pro day, not because Lynch saw him.
On top of that, here is a post from awhile back showing the Bay Area writers knew where Zach was going, as well as the betting odds. Zach was -5000 to go to New York on the day of his pro day.
