He threw for over 300 yards in last season's playoff loss vs Cincinnati in the cold. He's fine in the cold.
But he was 29/54 (25 misses) with 1 TD and 1 INT in a loss
Burrow was 24/34 with 2 TD and 0 INT
Even if he plays well in cold it doesn't mean he likes it enough to live in it.
When you play you warm-up and stop feeling cold
When you run out to get the paper in the frosty AM you can be like "Eff-it this sucks" lol
