Dallas won't be able to throw deep passes in a cold, windy, potentially snowy Lambeau environment.
Prescott's splits in cold weather vs. warm or indoors are pretty gargantuan. Today another one of those cold, windy days, though nothing like Northeast Wisconsin in mid-late January.
Environment does matter, like it or not. Prescott, born and raised in the Deep South, was able to post good stats at Tampa in week 1 against a great defense for a reason. Denver stinker loss aside, he's been superb at home. Arizona and LA play indoors and TB plays in a toasty winter environment.
There's one stadium that a Dak Prescott-led offense does not want to go to in January, under any circumstances... it's not Jerryworld, either.
