From my POV, which is that defense is stupid and only Fields really matters, it was fantastic. Watch this touchdown throw at 5:10:
He drops back, he goes through his progressions, and the *instant* he looks at the WR he throws it in rhythm. The WR isn't wide open, but it's man coverage and Fields throws to the receiver's leverage to get enough of a window for the catch. Exactly what he didn't seem able to do early in the season. I'm struggling to think of many plays I would ding him for. He underthrew a deep ball early, but he threw a perfect one later.
