He actually moved the ball pretty well today while behind in the 4th quarter, tbh. He had a TD drive and two other good drives, one where they barely missed a 4th down conversion and the other where they ran out of time after a shot at the end zone.
His problems were the turnovers he had while tied or ahead, tbh. In any case, he's still one of the best QBs in the league. The Ravens where before he took charge and now they are one of the best teams in the league. The entire Ravens' run offense works thanks to Lamar running ability and his vision to run the option. That said, yeah, he will need to improve a bit more as a pocket passer.
