Here's a quote from Patrick, the bolded part I could never see Josh or a number of other top tier QBs saying:
"We can move the ball on pretty much every coverage," Chiefs quarterback Patrick Mahomes said. "We have answers for every [defense]. But you've seen it every game pretty much that there's been times when we stall out or we don't execute or I throw the ball and I don't hit the right spot or the receiver doesn't see it the same way I do or penalties or turnovers."
every bad game Josh has had he always says things like "I need to be better" or "this is on me." he never groups in the team with the loss, he rarely uses the word "We" after a loss, it's always "me." The "We" stuff comes after wins not L's.
