On the second pick of Maurer - who immediately went up to Palmer and told him what he should have done? Palmer paid attention to what he said.
Callaway.
In a previous game, who told JG on the sideline on the pick he threw that JG misread coverage.
Callaway.
Callaway knows. All receivers are coached to moved toward the QB in those scramble situations. When Palmer saw Maurer was coming his way in a scramble situation he is supposed to move toward him, not stay along the end line for the jump ball. Maurer should not have thrown it, but he trusted his receiver to hold up his end. He didn't. Just like JG not reading the corner jumping the out with Callaway. If the corner jumps the route, the QB holds the throw and then delivers a quick, hard, pad level throw to the receiver on the up move before the S arrives.
FWIW, Callaway will be the consummate professional in the league. VFL.
