[*jason*]

Wanna know the biggest difference between the 2015 and 2021 teams? The 2015 team had loose cannons who blew their cool when it really mattered. The 2021 team didn't have that... They played with poise. The 2015 team went toe toe with one of the best teams in the league that year. They did that without their QB who was having a career year. The had the Steelers beat, then completely melted down. The 2021 team kept it together even when they were getting rolled.
