When he threw the ball to JPP, clearly he thought Henderson was going to stop and turn around. Hopefully he learned that on screens you can't anticipate like you do routes that are fun. You MUST see the RB looking you in the eyes before you throw the ball because they are always navigating traffic.
The fumble was on him.
Not entirely sure about the other INT, but it looked like it was on Goff.
But this is a young man that doesn't go into a shell. He reminds me of Rogers this way. Both of them will have a bad day throwing and keep on slinging it without blinking.
