That was classic vintage game-manager Russell.
The winning TD throw was also classic Russell too. He still doesn't truly read defenses, but he read the coverage and the receiver position and knew the favorable matchup, and he had decided pre-snap that's where he was going, to his Dawg, Cortland Sutton, and that he'd throw him a jump ball he knew his guy would win.
Other classic clutch Russell:
1) 2013 NFCCG vs 49ers, 49ers jump, Russell and the receivers recognize the automatic 4-verts route adjustment and all do it, Russell hits Kearse for a 45 yard TD.
2) 2014 NFCCG vs Packers, OT, Russ recognizes Zero Blitz by GB, gets just enough time, and hits Kearse for the walkoff TD.
