This game was winnable for Cleveland. The moment Mahomes was out and Cleveland's offense started to roll KC was in danger.
But getting that interception and doing nothing (while killing almost all of the clock) and then letting Henne run wild on that 3rd and 13?
Also, while it was gutsy to go for it, maybe Henne was told to throw a short pass to Hill if he sees the chance, and Cleveland was not prepared. Even the announcer was thinking there would be no snap (watching on ESPN Latin). Gus=tsy call that could have gone wrong in many ways, but also very badly played by Cleveland.
I think that the Browns have a future in the NFL. Mayfield is finally playing like a 1st round pick, and they have a very good cast around him. Let's see.
