Watch Aaron Rodgers play and see how his receivers are always adjusting for his tight level throws. That's what NFL receivers do. Rodgers has Devante Adams and then all blue collar guys who aren't gonna out athletic many people, but they know how to be on the same page with their QB and execute.
Again Tua probably shouldn't make that throw knowing that we're dusting off crap to run out an offense. But if that is to a guy that belongs in this league that throw is a sign of Tua's greatness, ascendancy, and ability to throw between defenders.
