Technically, refreshing a website has sh*t to do with factual information that's been the same for months. Since you seem to be having great difficulties with the simple certainty that Tomlin is indeed 8-9 in the playoffs, I'll spell out the details for you (I'll try to type slowly):
Tomlin has coached the Steelers for 15 seasons. His teams have made the postseason 10 times.
Super Bowl win (2008): 3-0
Super Bowl loss (2010): 2-1
AFC Championship loss (2016): 2-1
Divisional round loss (2015): 1-1
Six others one-and-done: 0-6 (not 7 as you indicated above)
Now, if you add up the grand total there, my friend, what do you get? Why, yes, it's 8-9! See how that works? Amazing!
Jesus Christ. No, it's not been 4 seasons since the Steelers made the playoffs, since they made them last season. It has, however, been FIVE seasons without a postseason win, which last came in January of 2017 (the conclusion of the 2016 season).
Let's count them together!
No playoff wins in the 2017 season...one!
No playoff wins in the 2018 season...two!
No playoff wins in the 2019 season...three!
No playoff wins in the 2020 season...four!
No playoff wins in the 2021 season...five!
Yay!
All cleared up, big guy? Ready for a Juicy Juice?
