One of Dak's worst features is his tendency to be overcautious. It's just not his game to try and fit those tight balls in, or throw to the spot and let the receiver make a play. He the polar opposite of a guy like Allen. Dak was "coached up" to be more aggressive and the ints went up.

“I got away from how I play this game — I got greedy,” Prescott said (via the Dallas Cowboys team website). “I tried to force some throws, take the big ones, and that’s not who I’ve been in my career. … So it was a way for me to just dial back in, but I wiped that clean because I knew what this game meant.”
