My take: He was scared to death to throw another interception on national tv and his confidence was shattered..
instead of throwing the ball on instinct he was looking to long to see if there were any browns in the area who would be able to intercept the ball. By the time he determined it was a safe pass it was too late, the timing was off, the defense had read his eyes and covered the play or else the rush was there and he had to dump the ball off. Or he did not have any confidence that the receiver would be where he was supposed to be and was afraid to let the ball fly early.
