Worth pointing out that Ramsay destroyed Jon in tactics. Like, humiliated him. Sure Jon was the underdog going in, but if this was a football game, it was 48-0 in the second quarter. He lured Jon and his army into a charge by using Rickon as bait. Showered the field with arrows to pile up the bodies to completely stop their charge/movement. Sent in the Calvary to drop more bodies and corral everyone into one small space. Sent in the shielded solders to employ the phalanx, while the Umbers closed the exit. Battle over before it's even time for lunch.
Davos couldn't save the mess that Jon created by abandoning all of their tactics.
Starkset might need a new coach in the wars to come.
