There is a better scenario we should be rooting for where we don't even need the Titans to lose.
If the Browns beat the Jets, and the Colts win, we basically clinched the 2 seed. Except for a tie in this scenario, the winner of the Cleveland vs Pittsburgh would have the same record as us. We would win any tiebreaker over the AFCN teams, and they would also create a 3-way if the Titans win out. We win all 3-way ties.
So it's easier to root for the Browns beating the Jets, instead of the Packers beat the Titans. This is the easier scenario, but it isn't guaranteed because of potential ties.
